Yup. I tried putting:
$SIG{CHLD}='IGNORE';
in my parent and that prevents the zombie child. So, next question!
how do I wait() or waitpid() on more than one process? don't both of
those make the wait()ing process sit still and do nothing else until
it gets a return? I'll read perlipc again (man that's a hard one to
grok) and see what it says.
