Then I guess it would be better to just push those changes and see if
they do any harm.

I never use the master branch for serious work, so it doesn't matter
what I do. In addition, I almost never shut down my systems.

If a window procedure doesn't process messages for more than 5 sec,
Windows will put "Not Responding" on its caption bar. So I think the
100 msec number in Ken's patch should be changed to something like
6000, and then we are fine, because even on a busy system this should
be long enough. And if Emacs (and the OS) is about to shut down, it's
even less of a problem to ignore a message that timed out, IMO.
