    This is a workaround rather than a fix.  A real fix would be to change
    sit-for so it doesn't use unread-command-events but an internal variable
    instead with which other code can't mess.

I disagree.  unread-command-events is defined to do what it does.  If
Lisp code sets it to nil, that gets rid of the pending events.  If
Lisp code later sets it back to something non-nil, that restores them.
If the result of doing that isn't what you want, you should not do that.
