One possibility is to create an account for the task you wish to
perform and give it an appropriate CPU limit.  When the limit is
reached, the process is killed.

Another possibility is to write a simple program which calls $CREPRC to
create a process to run your task.  $CREPRC can be given a CPU limit.

Hope this helps.
