Could the problem that users unsaved data are not saved on w32 in this 
situation be put in FOR-RELEASE? I think it is a serious bug.

I have already sent a patch for this, but I have got no response on 
that. There is possibly disagreement on what to do, but something should 
be done and I do believe that the correct fix should make Emacs follow 
the guidelines on w32. Jason said he had read them. I asked for a link 
to them, but I have not seen it yet. Instead I provided the above snippet.
