Back in the days of 2 IDE drives on PIO, 2 SCSI controllers with tape drive, scanner and 7 SCSI drives ranging from 0.5 to 2GB each I wrote a class for a round-robin schema for "temp tables" with automatic cleanup - having cursors settle on different physical discs would have eliminated most of that code ;-)
