The thread seems to be at 
(although I do seem to recall more discussion of the patch which I 
currently can't find). I'd be very surprised if any applications rely on 
the fact that each process starts counting at zero, so if someone can 
come up with a high-res counter which avoids that artifact I'd expect it 
could be used.
