If you just want to avoid zombies and don't care about the return
status, you can set SIGCHLD to SIG_IGN with SA_NOCLDWAIT (see
sigaction(2)) and not have to use wait() at all.

Note that if you don't bother to wait() for children and don't otherwise
keep track of how many children you have, you can run into overload
problems if you start creating children faster than they complete.
