OK, I finally got around to testing it. Yep I see your point. Do you
think it should go to 3.16 and stable? I can add it to my next git pull
request.

Also, I modified your test such that it wouldn't hang on failure, but
detects that it hung and returns a exit value to add this to my
testing. That is, it exits with zero on success and non zero on failure.
