  Log:
  SVN rev 182879 on 2008-09-08 21:40:15Z by jhb
  
  - Reduce scope of #ifdef's in uma_zcreate() call in init_turnstile0().
  - Set UMA_ZONE_NOFREE so that the per-turnstile spin locks are type stable
    to avoid a race where one thread might dereference a lock in a free'd
    turnstile that was previously used by another thread.
