Updating to 0.4.0 caused an application I work on to stop working. Investigating, I found that getting rid of autoreset=True fixed the hanging problem, but I need the autoreset behavior.

Working through the changes since 0.3.9, I found that reverting a3eabd2 fixes the problem. This the merge for PR #164.

I've not nailed down why this affects me - I'm not using PyCharm - but I expect you'll hear from others as this update proliferates. If I can pin it down I'll submit a PR.
