I've only had a first glance at both of these proposals and n2178
looked more natural to me in the way of C++ interface is implemented.
The only thing I didn't see in it is TLS support for C++. Is it
planned to be proposed later or did I miss it? IMHO, it should be
supported in <thread> in some way in order to provide the standard way
of destroying thread specific data on thread exit. Maybe thread
barriers support would be a nice addition too.
Another thing that bothers me is weither pthreads should become a part
of the C++ Standard. Yes, it is indeed a wide-spread threading
implementation, but should it be mandatory API for any C++-compatible
platform? Maybe the <pthread.h> should stay behind the scope of the
Standard and <thread> should be official C++ threading support (yet
internally it may still be based on pthread or any other low-level

IMHO, the best way to go on is to evaluate the design. IOW, to
implement the proposal and compare it to competitors in a set of
wide-spread use cases.
