    test - Add lockmgr1, lockmgr2, lockmgr3 tests
    
    * Add tests which perform various system calls intended to exercise
      lockmgr() locks.
    
    * Generally shows a roughly 40% improvement in SMP performance
      from the recent lockmgr changes when shared locks have high
      collision rates.
