I might be wrong in many ways, but...
is it then mandatory that you `reset' SIGCHLD to SIG_DFL ?
Why not leave it in it's default state, and make this patch:
- signal(SIGCHLD, SIG_IGN);
without adding any lines?
I'm in a wild rush, and I don't have the time to actually look at the code or
test it. I will, soon, though...
