Review Comment:
   After short discussion with @dvarrazzo  - it's likely this 
https://github.com/dvarrazzo/py-setproctitle/pull/144 is going to fix it 
(unreleased yet).
   
   It would be great though to get some more details about those segfaults 
@jaketf @ashb when you see them happening again ?
