Comment 5 for bug 1662544

Here's my work, split in nice, small commits:

I've been running it for a couple of weeks, no crashes and no exceptions. It just works flawlessly, at least for the use that I give it. There surely are bugs in codepaths that I don't use, so some wider testing would be appreciated.

There are a bunch of shebangs still pointing to python2, but we should just delete those I guess.
