Event MPM - CLOSE_WAITs

[Greg Ames]

I have Paul's version of the Event MPM patch up and running.  The only glitch I 
saw bringing it up was a warning for two unused variables in http_core.c 
(patchlet below).   Then I tried stressing it with SPECweb99 and saw some errors 
after several minutes:

[error] (24)Too many open files: apr_socket_accept: (client socket)
...and a few others with the same errno.  Digging into it a bit, sockets are 
hanging around with netstat showing an abnormally high number of CLOSE_WAITs. 
We must be missing a close() somewhere.  Maybe in the timeout logic?  I believe 
that was reworked.

If no one beats me to it and day job permitting, I'll investigate further next 
week.
