Arm periodically freezes

Arm version 1.4.4 had an issue where it froze after running for several days. I managed to get a reliable repro for this sort of glitch and tracked it to an interaction between readline and screen which has been fixed in 1.4.5, but the original problem persists.

At this point I'm at a loss for what is causing it or how to diagnose the problem since it takes days to manifest. At present I'm trying a sort of git bisect to narrow down the issue. I'll update this ticket as I narrow things down.
