SIGCHLD, fork, listen

I'm trying to set up a fairly "simple"
server that listens for a socket connection,
forks off a process and goes back to listening.
This works fine for multiple clients, except
I get zombies. I try redefining SIGCHLD as
SIG_IGN, but this doesn't work (as apparently
is what's expected under POSIX). I then
try redefining it with my own function that
includes a WAIT. Fine, except "listen"
doesn't get signalled when the child process
dies, only when the next socket connection
occurs. (which could be hours later, not
good).
So is there a simple way to get around all this?
A higher piercing SIG to get through to "listen"?
A different flag? I split this out into 4
servers before to get around this, but it's
kind of ugly/wasteful.
Thanks,
Bill
