  HAMMER 61F/Many: Stabilization w/ simultanious pruning and reblocking
  
  * BUG FIX: When doing direct-read check to see if any device buffers
    are aliasing the disk block and flush any we find which are dirty.
    This ensures that reblocked data gets to disk before a direct-read
    tries to read them FROM the disk.
  
  * BUG FIX: Fix a bug introduced in a recent commit where the flusher
    wlll not always completely flush the UNDO FIFO or completely flush
    all meta-data, resulting in a rollback after a normal umount/mount.
  
  * BUG FIX: Direct-writes queue I/O independant of the in-memory record.
    When the backend flusher flushes the record, making it available in the
    B-Tree, make sure that the indepent I/O has completed.  Otherwise
    a later reblocking operation might read the media before the direct-write
    has actually completed.
  
  * BUG FIX: In-memory records are not subject direct-IO, since their data
    is not yet on the media.
  
  * BUG FIX: Do not allow mount to succeed unless all volumes have been found.
    (Reported-by: Sascha Wildner <saw@online.de>)
  
  * BUG FIX: The bd_heatup() call in the reblocker was in the wrong place,
    potentially causing the cursor to shift unexpectedly.
  
  * Reorient some of the buffer invalidation code by enhancing
    the reservation code.
  
  * Add read CRC verification logic for some direct-reads, but comment it out
    because the VM system's bogus-page replacement breaks it.
