  SVN rev 204950 on 2010-03-10 13:23:25Z by jhb
  
  Use thr_once() with once_t controls to initialize various thread_key_t
  objects used to provide per-thread storage in the RPC code.  Almost all
  of these used double-checking with a dedicated mutex (tsd_lock) to do this
  before.  However, that is not always safe with more relaxed memory orders.
  There were also other bugs, such as one in __rpc_createrr() that caused a
  new key to be allocated each time __rpc_createrr() was invoked.
