We could put a bit in ul_global and have the __pthread_prog_init code set it
up, in the absence of better places? I'm not particularly au fait with the
Unixlib code either, so open to better solutions.
I can do some implementation and testing, if this is deemed to be a good idea.
('testing' in a loose sense - provoking concurrency conditions being somewhat
hard)
It does mean rebuilding Unixlib static-linked programs, since it isn't in
the tiny part of code that lives in SharedUnixLib. That's a bit of a pain,
but easier for the things we have autobuilt and packaged.
