A better solution than my previous commit as pointed out by Andre Malo.

dropped connections.

Such bytes were counted on some paths but not on others.  If
these bytes are to be counted in some error paths, they should
be counted in the others.  We don't know if they were actually
presented to the client.

AFAIK, this only affects mod_logio.

mod_include.  Now it works like 1.3 (see PR for details).  Setting
of envvars for scripts was/is consistent with 1.3 for empty variables.

  (listener_thread): create and add sockets to the pollset using the new
    APIs. rearrange the round-robin a little bit to work with the new
    pollset return values.
    cleaning: get rid of an extraneous status variable. get rid of
      obsoleted round-robin code.

* server/mpm/prefork/prefork.c:
  (listensocks[]): removed. not required.
  (child_main): stop using listensocks[] in favor of an apr_pollset_t. if
    there is just one listener, then always refer to that listener's
    listen_rec for further processing, otherwise poll and pick up the
    listen_rec pointer from the polling structure's client_data. tweaked
    the round-robin for the new pollset API (and documented).
    cleaning: removed 'offset' which is obviated by the use of a pointer
      to a listen_rec. tighten the block-scope of several variables.
      switch to use a 'status' variable name rather than three separately
      named variables. rename n->numdesc to be more obvious.

AIX.

On AIX, for processes like mod_cgid's script children where
SIGCHLD is ignored, kill(pid,0) returns success for up to
one second after the script child exits, based on when a
daemon runs to clean up unnecessary process table entries.
getpgid() can report the proper info (-1/ESRCH) immediately.

One user had a page with a lot of embedded images created by
CGIs, and the browser fetched them on a keepalive connection,
and the cumulative delays were very noticeable by the clients.
