Could probably find the commit that removed it and restore or at least
see if the warpin script was in the tree.

There's a lot of stuff still left over which refers to OS/2, which is
why I didn't think anything had really been changed.

That said, is pthread so bad vs native threads? I'm still just getting
started testing this build, so I can't really comment on performance,
yet. I was just surprised that I can generally find all other libs for
building things, but this seemed to need an explicit pointer with a full
path.
