Also, check c->aborted before apr_socket_shutdown() because it is set earlier,
and there is no point in calling shutdown() before close().

close support in Event. these are set by the listener due to a residual
c->sbh for a worker thread no longer associated with the connection.
the associated worker threads are really idle and blocked in
ap_queue_pop_something and will serve new work normally. but since they
are marked as SERVER_CLOSING rather than SERVER_READY in the scoreboard,
the parent process thinks they are busy and forks extra children.
reproduction recipe: start Event with server-status enabled. hit
localhost/server-status?refresh=5 and watch the C's trail behind the lone W.

- 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.

We know that the core module has module_index 0. Therefore we can save
some pointer operations in ap_get_module_config(cv, &core_module) and
ap_set_module_config(cv, &core_module, val). As these are called rather often,
this may actually have some (small) measurable effect.

Add an allocator-passing mechanism throughout the bucket brigades API.
From Apache's standpoint, the apr_bucket_alloc_t* used throughout a given
connection is stored in the conn_rec by the create_connection hook. That
means it's the MPM's job to optimize recycling of apr_bucket_alloc_t's --
the MPM must ensure that no two threads can ever use the same one at the
same time, for instance.

- rename the create_connection hook to install_transport_filters
- move the point of invocation of the hook till after the call to

abstracted some of the logic out of the lingering close so that it gets
the socket from the connection using the core's conn_config vector. This
is in anticipation of a change to use a hook for the lingering close,
which I hope to do soon.
