  Log:
  Revert the previous race fix and replace it with a more general fix.  The
  case of a turnstile having no threads is just one instance of the more
  general case where the thread we are examining has been partially awakened
  already in that it has been removed from the turnstile's blocked list but
  still has TDI_LOCK set.  We detect that case by checking to see if the
  thread has already had a turnstile reassigned to it.
