The Event MPM.

Browse Source 
Designed to minimize Apache's KeepAlive overhead.

This MPM depends on the current APR-trunk for new features added to 
the apr_pollset interface. Currently the underlying operating
system must support KQueue or EPoll.

Status:
  Should work as a drop in replacement for all non-ssl servers.
  SSL Requests that use HTTP 1.1 Pipelining do not currently work.

Testing:
  I have tested it with Linux 2.6, FreeBSD 5.2.1, and OS X 10.3.
  
Originally based on the patch by Greg Ames.
