  Log Message:
  -----------
  Implement a --timeout option. Set it to 5 minutes by default.

In some cases creduce could make the compiler end up in an infinite loop. The
timeout should abort the current transformation and reject it.

  Kill the timing out process.

Perl alarm just throws an exception it doesn't kill anything. Try using the
killem routine to do the job.
