A user runs "emacs -nw" within xterm, and often stop them with CTRL-Z to
keep them in background. Now Emacs loops and hogs both memory and cpu after
shutting down X11 going to runlevel 3. Likely this was a leftover emacs from
background.

For the case you posted, it is safe.  delete_frame is called with force set to 
Qnoelisp, which is not NILP (force) so the test is not run.
I've checked that in, it fixes this bug.
