  Log:
  Add the MPIPE subsystem.  This subsystem is used for 'pipelining' fixed-size
  allocations.  Pipelining is used to avoid lack-of-resource deadlocks by
  still allowing resource allocations to 'block' by guarenteeing that an
  already in-progress operation will soon free memory that will be immediately
  used to satisfy the blocked resource.
  
  Adjust the ATAold code to use the new mechanism and remove the code that
  tried to back-off into PIO mode when resources were lacking.
