Not waiting on #cvs.lock

[gilmurra]

I'm doing a "cvs update -P -d ..." every two hours from a cron job.
Everything works fine 'til somehow a #cvs.lock doesn't get deleted.
Every two hours another update job starts and eventually we run out of
job space. I realize some locks are valid and I'm writing a script to
inform me when a lock is more than one day old but that won't solve my
immediate problem.

Is there a way to abort instead of waiting when a lock is set when doing
an update? 

Thanks, Frank
