within apr_socket_timeout_set, let's presume that vendor differences
of socket stack drivers can vary this behavior, and the assumptions
were unsafe for both accept() and AcceptEx().

sockets; it appears that resetting the accept event while another was 
waiting would break the pending connection, causing host socket resets.

 * drop a frequent query for the mod configuration (pass as f->ctx)
 * drop one copy, at least for ASCII

and ensure larger buffers are logged in their entirety.  Some clarity
in output can be added by designating continuations vs first lines.

This facilitates the next two refactorings; multiple listeners per
listener thread (all accept paths using win32 events) and then multiple
threads leveraging parallel CPU's.

with kqueue (BSD/OS X) and excessive CPU with event ports (Solaris).

The apr_pollset API requires that a socket be removed from
the pollset whenever there is a change to the requested events.
The socket must also be removed when it is closed.  This wasn't
completely implemented.
