  SVN rev 184497 on 2008-10-31 09:09:22Z by davidxu
  
  Merge revision 183061 from head to stable/7.
  
  > Allow multiple locks to be acquired by detecting corresponding
  > bit flag, otherwise if a thread acquired a lock, another thread
  > or the current thread itself can no longer acquire another lock
  > because thread_mask_set() return whole flag word, this results
  > bit leaking in the word and misbehavior in later locking and
  > unlocking.
