I don’t think SIGQUIT handling is a big problem. But even with the new change, it is still easy to screw up the terminal in many cases, so I wouldn’t say this is fixed yet. Steps for Python 3 in a small 80 × 25 terminal on Linux:

* import _pyio; help(_pyio)
* Hit Ctrl-C

Steps for Python 2:

* import _pyio; help(_pyio)
* Hit Ctrl-C
* Hit Space ten times to scroll down. Alternatively, hit Ctrl-C a second time.

I am posting a quick patch which I think should fix this in Python 3 by deferring the traceback until after the child has finished. Another method is using the signal module like <https://github.com/vadmium/pacman-tools/blob/9ffdd88/roopwn#L976>, but that’s probably too platform-specific for the pydoc module.
