[Tinymux] Ontime bug in Win32 TinyMUX

[Stephen Dennis]

There was a small window of opportunity (only a few instructions) in
forking dumps that games of just the right size can hit. As far as I
know, only 5 games on cheshire at mushpark have hit it. The fix is in 2.4
already, but its been tested enough that it's time to backpatch it to
2.3. The main server process never realizes that the child process has
finished already. If you've run into this, let me know.

Also, there are two people (Thanotos and David at Exalted) who are
running into time problems on Win32 for which I have added more
protection. Maybe Thanotos and David at Exalted will be gracious enough
to tell me whether it gets 'better' or 'worse'.

I'll try to do another round of releases this weekend.
