Comment (by alex@…):

 Updated the patch with a minor fix.

 Also note that as mentioned in the original description, we can
 alternatively keep most of the existing implementation the same and use a
 pthread_spin_lock instead of a boost::mutex to guard the internal state.
 This will make the implementation quite similar to the win32 one.
