  HAMMER 61A/Many: Stabilization
  
  * Fix a buffer exhaustion issue.  When creating large numbers of empty files
    a single inode sync of the directory can exhaust the buffer cache because
    not enough other things get dirty enough to force a flush.
  
    Put a check in the record syncing code and do a partial finalization if
    necessary to avoid deadlocking the buffer cache.
  
  * Fix a panic caused by a missing call to hammer_cursor_deleted_element().
