I suggest you use a nil timeout in Emacsā‰„27.  If this reveals there are
still remaining bugs, we should fix them rather than work around them.

If the bugs have all been fixed already, then maybe we could also use
a nil timeout in older Emacsen, but we've lived with 0.1 in them, so
I think it's OK to keep using a suboptimal value there.
