You don't need to, you jnust need to wait for ll the dead children to
go. 

if you ...

while ($pid = waitpid(-1,&WNOHANG) > 0) {

      # do something with $pid, or not
}

Then you'll wait for everyone to die.

Alternatively if you IGNORE the SIGCHLD, then I believe the system
will just sort it out for you.

$SIG{'CHLD'} = 'IGNORE';

This is a good option when you want to do nothing with the children.
