Hi Boost,

I was surprised to see an internal mutex added to 
boost::condition_variable implementation in the recent versions of 
Boost. Quick internet searched revealed that this was done to better 
support thread cancellation:

http://permalink.gmane.org/gmane.comp.lib.boost.devel/210235

That thread ends with a suggestion to add back a zero-overhead 
pthread_cond_t wrapper and no reply.

So I was wondering whether there plans to reinstate that wrapper or 
should Boost users that are not concerned with thread cancellation but 
are rather concerned with code performance drop using 
boost::condition_variable and resort to writing their own wrapper?
