Eli, any change to have this backported to emacs-26?

This reason I'm asking is, this fixed a rather nasty bug resulting from 
the interaction between the newest company-mode (0.9.5) and 
flyspell-mode, both of which use sit-for. This particular combination 
results in a timer being run inside a sit-for, which also calls sit-for, 
which in emacs-26 ends up putting e.g. (t t . 45) into 
unread-command-events.

Here's how to reproduce:

- Visit the attached file.

- M-x eval-buffer.

- Start typing.

- See "<t> is undefined" in the minibuffer for every other keypress.
