This results in clean error messages in an out of memory situation instead of
segfaulting or silently malfunctioning. In some places, it just allows to
remove some logging code.

- Process lingering close asynchronously instead of tying up worker threads
(based on patch by Jeff Trawick).
- If the number of connections of a process is above
threads_per_child + WORKER_OVERCOMMIT * (idle_workers - 1)
(WORKER_OVERCOMMIT is fixed at 2, at the moment), or if all workers are busy,
don't accept new connections in that process. Such a dynamic connection limit
is necessary because we may have both async and non-async (ssl) connections.
WORKER_OVERCOMMIT should be a config option.
- Don't count idle workers of not-accepting processes against MinSpareThreads,
so that the parent will spawn new processes when necessary.
- If we receive a keep-alive request while all workers are busy, don't block
but close the connection immediately so that the client will re-connect to a
different process.

this URL prefix is mapped to). This generalization of the document
root makes it easier for scripts to create self-referential URLs and
to find their files.
- Expose CONTEXT_DOCUMENT_ROOT and CONTEXT_PREFIX as envvars, in mod_rewrite,
and in ap_expr.
- Make mod_alias and mod_userdir set the context information.
- Allow to override the document root on a per-request basis. This allows
mass vhosting modules to set DOCUMENT_ROOT correctly.

Using this basic framework, you can return SUSPENDED from an HTTP Handler,
and then register a callback that is invoked by the MPM at a later time.
This initial version only supports _timers_ as callbacks, but in the future I
would like to add things like wait for socket activity, on a socket specified by
the handler.
Once in a callback, It is then the responsibility of the callback fucntion
to finish the HTTP Request handling, but this alows you to do cool things like
a fully async proxy, COMET support, or even rate limiting.
To prove I'm not insane, I've inlcuded an example module, mod_dialup.
You can configure it like this:
<Location "/docs">
ModemStandard "V.32"
</Location>
And for static files inside that path, you will be rate limited to V.32 speeds,
aka 9.6 kilobits/second.
Does anyone besides Rüdiger read commit emails :-) ?
I know there are likely huge problems with this, but I would like to see how far
we can push the Event MPM, figure out what to do better, if there is anything,
and then really dive into the 3.0 development before ApacheCon.
* server/mpm/experimental/event/fdqueue.h:
(timer_event_t): New structure to hold timer events and callback functions.
* server/mpm/experimental/event/fdqueue.c
(ap_queue_empty): Modify to also look at Timer Ring.
(ap_queue_init): Initialize Timer Ring.
(ap_queue_push_timer): New function, pushes a timer event into the queue.
(ap_queue_pop_something): Renamed function, returns a timer event or
a socket/pool for a worker thread to run.
* server/mpm/experimental/event/event.c
(process_socket): If the connection is in SUSPENDED state, don't force it
into linger mode yet, the callback will have to take care of that.
(push_timer2worker): New shortcut function, pushes timer event into queue
for a worker to run.
(timer_free_ring): New global data structure to recycle memory used by
timer events.
(timer_ring): New global data structure to hold active timer events.
(g_timer_ring_mtx): Thread mutex to protect timer event data structures.
(ap_mpm_register_timed_callback): New Function, registers a callback to be
invoked by the MPM at a later time.
(listener_thread): Calculate our wakeup time based on the upcoming Event
Queue, and after pollset_poll runs, push any Timers that have passed
onto worker threads to run.
(worker_thread): Call new queue pop method, and if the Timer Event is
non-null, invoke the callback. Once the callback is done, push the
structure onto the timer_free_ring, to be recycled.
(child_main): Initialize new mutex and ring structures.
* server/config.c
(ap_invoke_handler): Allow SUSPENDED aa valid return code from handlers.
* modules/http/http_core.c
(ap_process_http_async_connection): Don't close the connection when in
SUSPENDED state.
* modules/http/http_request.c
(ap_process_request_after_handler): New function, body pulled from the old,
ap_process_async_request. Split to let handlers invoke this so they
don't need to know all of the details of finishing a request.
(ap_process_async_request): If the handler returns SUSPENDED, don't do
anything but return.
* include/ap_mmn.h: Bump MMN.
* include/ap_mpm.h
(ap_mpm_register_timed_callback): New function.
* include/httpd.h:
(SUSPENDED): New return code for handlers.
(request_rec::invoke_mtx): New mutex to protect callback invokcations
from being run before the original handler finishes running.
(conn_state_e): Add a suspended state.
* include/http_request.h
(ap_process_request_after_handler): New function to make it easier for
handlers to finish the HTTP Request.
* modules/test/config.m4: Add mod_dialup to build.
* modules/test/mod_dialup.c: New rate limiting module, requires the Event MPM
to work.
