  Modified files:
    sys/sys              proc.h umtx.h 
    sys/kern             kern_umtx.c 
  Log:
   - Remove the blocked pointer from the umtx structure.
   - Use a hash of umtx queues to queue blocked threads.  We hash on pid and the
     virtual address of the umtx structure.  This eliminates cases where we
     previously held a lock across a casuptr call.
