If I set a global SIG{CHLD} = IGNORE is there any
possiblity of it propigating to the ultimate parent,
and thus to all the child processes? I'm worried that
if I use the global (even though that's what Stas
Bekmen does in his mod_perl book example) it could
possibly cause problems with the way apache forks it's
own worker processes.
No it can't propagate to the other children via the parent - there is no mechanism in Unix for this to happen. However if you keep setting SIGCHLD to IGNORE, then eventually you will have modified all the apache children processes yourself (without touching the parent).
