Sorry, but I am not sure If I understand what you mean.
Do you mean the windows version should be implemented on top of
pthread?

In the platform split I took the following route:

1) Native platform API:
       this means win32API on windows,
       pthread where pthread is considered native
       possibly native linux, i.e. semaphores, fork, NPTL, ...

2) pthread API:
       For every platform where a pthread lib is available
       provide a pthread variant.
       I.e.: pthreads-win32, pthread on linux, pthread OSX, ...

In the end the user may choose from 2 library variants on platforms
that have both API's available.

If I may understand your sentence in this respect: Yes of course, we
should and will do this on windows.
