   Now, that's not silly at all, take that smack back immediately, you hear! 
It's well worth taking into consideration. Just checking for a lock file 
(EXEC_NOW.LCK), and if it's there wait ten seconds in a loop for it to be 
released, or something like that.

   The Billing crashmail program often spends a lot of time linking really 
large JAM files, and often new instances arrive trying to get a hold of 
crashmail -- but they have to wait in queue for ten seconds (over and over 
again if needed) until the previous guy is ready.

   Now you got me really thinking. I was just about to to to bed, you darn 
Aussie you...  ;)
