ap_note_subprocess is already in APR. I guess you're talking about the
code to restart a process when it dies?

Because the decision about when to restart a logging process and when
to give up on it is an application-level decision. If a piped logger
dies 3 times after only staying alive 1 second, do we bother to
restart it again? Maybe 5 segfaults is the right number to give up at.
Do certain types of death mean our behavior will change? SIGTERM
probably should always result in the process starting again, because
that's what the admin wanted. This might not be true for SIGSEGV.

I don't think APR should get in the business of making policy
