1. Under X11, with the GTK or Lucid toolkits:
emacs -Q
2. Become owner of the clipboard selection by killing some text; the
starting comments in the scratch buffer are a good candidate.
3. Immediately afterwards (i.e. without copy and pasting text in another
window), run:
(call-process "sleep" nil nil nil "inf")
4. Now other applications will hang when they attempt to paste text.
Google Chrome and Slack are two examples. (GTK-based applications
seem to be fine. So much for proprietary software...)
I guess Emacs doesn't handle requests for the X selection when in
call_process (which ultimately calls get_child_status).
It is regrettable that some other applications seem to not properly
handle a non-responsive X selection owner, but nevertheless ideally we'd
fix this in Emacs.
