You need POSIX::_exit here, or the END blocks get run twice (once for
each process).

Sorry, that's my mistake: exec() never returns, unless it fails, and I
tried to disregard every complication to make the point.

}
exit;

You probably want to wait here before exitting, as otherwise the execed
process is orphaned, and your parent gets SIGCHLD early. You probably
also want to set up signal handlers to pass signals along, etc... see
the source for the shell of your choice :). Or you could just use
system, which does all that for you.

Sure, this is just the extremely simplified version :-)
