Hi Jonathan, any update on this?

[jonathanslenders]

Hi @davidbrochart,

Could you remind me on how to reproduce it? I haven't looked at it for a while.
Right now, my focus is mainly on prompt_toolkit 2.0, then I'll rewrite pymux and pyvim on top of that.

[davidbrochart]

It looks like since I switched to Python 3.6, pymux always freezes after a while, with this error in the stack trace. But if you are going to rewrite prompt_toolkit, it may not be worth looking at it.
