Comment 4 for bug 1587554

Thanks for the information. BTW, we use Fuel-Devops 2.9.x, so the back port will be highly appreciated.
As a temporary solution for fuel-qa, now we close all ssh connections stored in SSHManager after all tests are done.

Regarding python crash - it's not resolved in python2.7, fix for http://bugs.python.org/issue1856 was reverted because of regression in cinder. And I'm pretty sure that we're not gonna use specific python version that contains the commit for bug not contains reverting commit.
