+Bug fixes
+---------
+Pthread_once has been re-implemented to remove priority boosting and other
+complexity to improve robustness. Races for Win32 handles that are not
+recycle-unique have been removed. The general form of pthread_once is now
+the same as that suggested earlier by Alexander Terekhov, but instead of the
+'named mutex', a queue-based lock has been implemented which has the required
+properties of dynamic self initialisation and destruction. This lock is also
+efficient. The ABI is unaffected in as much as the size of pthread_once_t has
+not changed and PTHREAD_ONCE_INIT has not changed, however, applications that
+peek inside pthread_once_t, which is supposed to be opaque, will break.
