Run the mypy daemon?

[tomv564]

Would be more performant, there is a risk with process management (does pyls provide a shutdown hook?), and the daemon doesn't support follow_imports?

I came here to offer the same suggestion. I think it would be great if someone could figure out how to get the performance of dmypy in a plugin for pyls. Then any editor would be able to access very fast type checking through Language Server Protocol.
