Minor point; this won't catch an error from fork(). If fork() fails, it
returns undef, and the test:
(0 == $pid)
Will be true, even if $pid is undef.
An alternate form is:
defined(my $pid = fork) or die "Couldn't fork: $!";
if ($pid) {
# child proceeds
...
exit; # child finished
}
# parent proceeds
...
