  HAMMER 38D/Many: Undo/Synchronization and crash recovery
  
  * The flusher now waits for I/O to complete at the appropriate points.
  
  * Implement instant crash recovery.  The UNDO FIFO is scanned backwards
    and reapplied to the filesystem on mount.  There is still more work
    to do here, inode<->inode associations (e.g. directory entry vs file)
    are not yet bound together.
  
  * Clean up I/O sequencing a lot and get rid of a ton of unnecessary flusher
    wakeups.
