keybind's update_keyboard_mapping takes a long time to run in python3

[inktrap]

Hi!

I did some work today to get pytyle3 and xpybutils to run on python3. Here are the results of what I did so far. This works mostly great!

There is one thing I don't get and even despite the fact that you stated a couple years ago that you don't want to work on xpybutil and pytyle3 anymore (we had some contact about this), I'll give it a shot; may you have an idea:

In xpybutil/keybind.py there is a check if there is a xproto.Mapping.Keyboard request. Then the keymap is updated. This update takes a long time to run and is very resource intensive. So much, that I can't use pytyle3. I added a return statement so the update is simply skipped.

I have the impression that this is run quite frequently and that other tilers do it too.

Why is it so costly? It is not supposed to take that long. When is this run? Any ideas how to fix this?

Thanks for the awesome work you did :) don't forget, pytyle3 has a clingy fanbase ;) <3
