Threading error when saving with neovim

Disclaimer: I've been using neovim with this plugin for nearly a year without any issues until the latest ctrl+p issue (#15 (closed))

For every save I get the following error. I am using the latest pynvim and this error does not happen when using regular vim.

Request from non-main thread.
Requests from different threads should be wrapped with nvim.async_call(cb, ...)
