If you need such code to work then use NeoVim. It is still not thread-safe, but NeoVim Python bindings run in another process and communicate via sockets and time of your code execution is controlled by NeoVim receiving messages and not Python sending them. Here you may need :redrawstatus to force statusline redraw, though I thought that setting &statusline should already cause a redraw. > > Another bad idea was using Python code using :pyfile.
