    HAMMER mirroring - Multiple adjustments to support better incremental ops
    
    * Read side - Ignore records created after the end point, reducing
      network bandwidth for incremental operations.
    
    * Read side - Generate PASS for records created prior to tid_beg, instead
      of pushing the whole record, reducting network bandwidth for incremental
      operations.
    
    * Write side - Ensure that deletions are end-exclusive.
    
    * Write side - Do not delete records created >= end point, supporting
      incremental operations.
