  comment = {More recent than copeland:bubba, and a little more general. This
  gives few details, and doesn't spend much time on the parallel I/O. Bubba
  does use parallel independent disks, with a significant effort to place data
  on the disks, and do the work local to the disks, to balance the load and
  minimize interprocessor communication. Also they use a single-level store
  (i.e., memory-mapped files) to improve performance of their I/O system,
  including page locking that is assisted by the MMU. The OS has hooks for the
  database manager to give memory-management policy hints.}
