bug#22878: 25.1.50; Emacs hangs on startup

[Mark Karpov]

I test startup of my Emacs on Travis CI with this python script:

https://github.com/mrkkrp/dot-emacs/blob/master/test-startup.py

Some time ago (last successful build was on February 22 2016), startup
started to hang with Emacs 25 master. I'm perfectly sure that this is
not due to my configuration. Looks like this:

https://travis-ci.org/mrkkrp/dot-emacs/builds/112443741#L230

I reported similar issue some time ago and it was fixed. I think it's
some sort of regression again. Perhaps you could add test to prevent
problems of this sort in the future?
