Depending on your cluster setup, it might be necessary to have some kind of dummy-queue with a cpu time limit of 10 seconds or so, which will always accept jobs (i.e. maybe a forced "mail_only" boolean complex, it could even reside on the master node).

That is a good solution, but it would rely on the users/is not automated.

The best "automatic" solution would be using an epilog script that 
checks qstat | grep $JOBID | wc -l == 1 and acts accordingly. But then 
again you have the problem of 2 jobs finishing at once (rare), and users 
that request "-m e" in their task jobs.
