No, that doesn't make much difference. It depends on the size of the message.
Appearantly 'cvs commit' doesn't unlock the files immediately so 
'cvs diff' started by syncmail gets caught in the lock. After a while
we had probably hundreds of 'cvs diff' processes started all waiting for
locks to be removed.

If you do it right the risk should be low. Also none of this runs suid root.
