Thanks Tim.

My default action is to try and match the prevailing style,
but  cut'n'paste propagated the flaw.  thread_pthread.h was
clean AFAICS, so I'll do a style normalisation (as a
separate checkin) on thread_nt.py and thread_os2.h when
commit time comes.

As an "implementation detail", I hadn't considered that
exposing it via threading was appropriate.

I can see 2 approaches:
- a simple shadow of the function as a module level function;
or
- a classmethod of the Thread class.

Any hints on which would be the more preferable or natural
approach?
