Yes, I've considered something like this, too. It does not give metis a
chance to terminate earlier, does it?

I've found:

  perl -e 'alarm shift @ARGV; exec @ARGV' 120 metis filename

(metis is big already, so the additional perl call can be disregarded.)

(In case someone wants to rewrite System.Timeout.timeout I would also
suggest to return the output produced until the timeout occurs.)
