  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.
