OK, that was a stab in the dark anyway.

I found a few problems in the code and fixed them in revision 110867
on the emacs-24 branch.  Please try the latest branch (without the
patch) and see if the problem persists.

Yes, that's one of the problems I fixed in r110867.  Shame on me.

(I think the fact that the handle to the caller thread was constantly
modified could be the reason for the lockup, if the change happened
between SuspendThread and ResumeThread calls.)
