Memory leak in 0.14.1

[zenmatt]

Tried upgrading from 0.13.1 to 0.14.2 yesterday. Ran into the issue referenced in #272 so rolled back to 0.14.1. Everything seemed fine for about an hour until the bot crashed. Restarted and monitored, only to see the memory was absolutely chewed up, started swapping and throwing errors again in under an hour. Rolling back to 0.13.1 resolved the issue. Can anyone else confirm this?

@zenmatt Did you get a chance to look into it at all?
