I keep having this problem myself. It only happens itermitently and I have no
idea why. Not accessing any remote hosts.

FYI... i figured out I have the issue when I am disconnected from

Hi guys, whats the status of this project? I know a few people (including
myself) who are ready to wave goodbye to Python 2 (its been 6.5 years now!)...
from an outside perspective looking it, Python 3 compatibility appears close!
