maybe i am missing something but how is this:

different than:
foreach my $user (@users){
my $UserPid = fork;
if($UserPid){
waitpid($UserPid,0);
}else{
#-- do stuff;
exit;
}
}
if @users has 500 elements, the fisrt version does 1000 forks.
the second version does only 500 forks
at last, only the main process's parent is living.
