[M3devel] results of threadtest program on Windows7

[Mika Nystrom]

Hi Randy,

You can try it with -tests POSIX as well.

I find on user threads it runs very slowly (but it does run) because of how unfair
the thread scheduler is.

Next step might be to whittle down the tests and see if you can get a failure with
a single test running and -n 2.  That would likely be the simplest scenario to
start further debugging from.
