* bug#21796: 25.0.50; exiting ediff can leave Emacs unresponsive to keyboard input

Recipe:

1. Start graphical Emacs with emacs -Q.
2. Create a buffer named "foo" with C-x b foo RET; insert the text "foo\n" there.
3. Create a second buffer named "bar" with C-x 4 b bar RET; insert the
text "bar\n" there.
4. M-x ediff-buffers foo RET bar RET
5. Either exit Ediff immediately with q, or move around and past the
single difference region with n's and p's, then exit.

With an appreciable frequency, after these steps Emacs is left in a
state in which it ignores any further keyboard input.  Mouse
interactions are unaffected, but not particularly useful with no more
keyboard input registering.  I have to close Emacs and restart, but if
Emacs asks me any questions before closing (eg. if I want to save any
modified files, or exit despite some processes still running), I'm
stuck; I cannot respond, so I have to open a terminal and kill the Emacs
process.

The same thing can happen if I use ediff-files instead of ediff-buffers.

The issue does not seem to arise if Emacs is run in non-graphical mode,
ie. by "emacs -Q -nw".
