If you can't then we should use an increment > counter, or not bother (Or am I being too exacting here?). Sorry, I meant multiple commits/sec. I think if there are multiple commits/sec, the chance of someone getting some of them and not all of them is almost nil, and given the fact that CVS doesn't keep this from happening (we have no locking), I don't think it's a problem we should concern ourselves with. If/when it becomes a problem, CVS will need some sort of locking protocol, and we can update the file in the middle of the lock. :) Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
