Vim is not thread-safe. You *must not* update statusline in another
thread, especially doing this using `set statusline` command (there is
also a variant where you use `vim.options` and/or {window}.options
({window}: object from vim.windows or vim.current.window)). Most
likely after some time this code is running you will get a crash
because Vim is using many globals (using .options will touch much less
amount of globals compared to vim.command('set statusline=' …)).
Another bad idea was using Python code using :pyfile. This command
pushes all variables/functions defined in the sourced file into global
namespace so with big amount of plugins that use :pyfile you will
definitely run into problems.
