Doing a cross domain iframe test.  `domain1.html` has iframe pointing at `domain2.html` which has iframe pointing at `domain3.html`.

`domain{1,2,3}.com` are all configured to point at `127.0.0.1` in my `/etc/hosts` file.

Loaded up `http://domain1.com:8000/domain1.html` in my browser and it spins waiting for domain3 to load.  CTRL-C and then domain3 loads.  CTRL-C again to quit.

Google chrome: 61.0.3163.100 (Official Build) (64-bit)

Same issue with python3
```
$ python3 --version
Python 3.6.0
$ brew info python3

```

Note only one CTRL-C to exit... but note it didn't server domain3.html...so stuck in the same place as before.  With python2 it serves domain3.html after hitting the first CTRL-C.  With python3 it never serves it, just quits after the CTRL-C and browser is "spinning" waiting for the file.
```
$ python3 -m http.server 8000

I can reproduce this EVERY time, but I can't imagine everyone has this issue or it would have been fixed already, so tried to provide lots of info about my environment.  Let me know if you need more.

There seems to be a similar issue on windows: https://github.com/Microsoft/BashOnWindows/issues/1906
