I cannot reproduce this: it does TRT for me.  At least I think I
can't; you didn't say how did you ``run the code'', so perhaps I did
it differently.  Using "M-x report-emacs-bug RET" would have helped
here, and would also supply the other missing information, which may
or may not be relevant.

This might be a Windows-specific problem (I don't have a Windows
version around to try).

What happens if you type C-g several times, when Emacs locks up?  What
about several presses on C-BREAK?  Does anything happen if you set
debug-on-quit to t and press C-g or C-BREAK several times when Emacs
locks up?

This is a sign of a continuous redisplay, not of an infinite loop.
