  SVN rev 214093 on 2010-10-20 02:34:02Z by davidxu
  
  Revert revision 214007, I realized that MySQL wants to resolve
  a silly rwlock deadlock problem, the deadlock is caused by writer
  waiters, if a thread has already locked a reader lock, and wants to
  acquire another reader lock, it will be blocked by writer waiters,
  but we had already fixed it years ago.
