You have to account for the return signals. Try this: 
#avoid zombies
$SIG{CHLD} = 'IGNORE';  # check if it works on your system

  for (1..100) {
       my $pid = fork;
             next if $pid;            # in parent, go on
             warn($!), next
     if not defined $pid;  # parent, fork errored out
       exec @cmd;               # in child,
       #   go do @cmd and don't come back
}
