Has anyone thought of a mechanism (similar to stuff I've seen on Masscomp machines) where one could indicate that a particular stream of disk I/O had a higher priority than normal? Masscomp used to have a B_URGENT flag for these blocks in the buffer cache (for semi-realtime I/O when acquiring or transmitting data). CD burners could do with this, or people trying to keep tapes streaming on backups. Stephen -- I do not speak for the Worker's Compensation Board of Queensland - They don't pay me enough for that!
