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.

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.
