  SVN rev 200498 on 2009-12-14 01:26:01Z by marcel
  
  Work-around a race condition on ia64 while unlocking a contested lock.
  The race condition is believed to be in UMTX_OP_MUTEX_WAKE. On ia64,
  we simply go to the kernel to unlock.
  The big question is why this is only a race condition on ia64...
