I've tested this both with bash and tcsh, BTW since tcsh's signal handling is
apparently different from bash.

This is what doesn't work here.  That is when I start the X server from another
mintty than the one that the X server is started from or when the shell is tcsh.
 So if I extend your case with:

6. Start another mintty

7. DISPLAY=:0 emacs -Q&

8. In the resulting emacs window, C-z.

9. Left click on the emacs icon to de-iconify emacs.

The cursor doesn't blink and emacs doesn't respond to keyboard input.

What do you get?

I thought about it, but I suspect that signal handling is involved and hence
cygwin1.dll.  Within the X server itself there seems to be no problem but maybe
I didn't try the correct sequence of events yet.

Achim.
