BlitzThreads (Windows only)

Urban legends aside, I've got too much going on project wise to try and implement any sort of multi-platform.
So here's the bmax/C++ source used, public domain so hopefully someone else can finish it off for us.(this won't be a commercial product from me. ever.)

anyway, enough rambling, here's the juice. (This is the latest version btw, I'd nab it if you're using the above.
You can now pass a pointer to a thread. (Edit-fixed a bug.)
