some tests just hang outside of tox runs

[RonnyPfannschmidt]

as far as i can tell its not possible to correctly test pytest outside of tox since years now
this is starting to impede my testing/re-factoring seriously

common issues happen with terminal/pdb tests

Can you give some direction about how to replicate?

I'm on mac, I was having trouble with a pdb test hanging until recently; fixed in #3116.

i was typically experiencing hangups when just using my normal testing virtualenv with pexpect availiable, (pexpect using tests would hang, i didnt yet verify against #3116

I just experienced this issue when running tests for https://github.com/vertica/vertica-python on osx.

EDIT: I installed tox via pip and that is version 3.2.1. Will pip catch up on the releases?

Closing as possible duplicate of #2673 (pexpect related), since this has no additional info, except for the hint to #3116.
