For the record.
A workaround is made in emacs 25.2 by introducing a dummy call to
(input-pending-p) in execute-extended-command--shorter.
A proper fix per Stefan Monnier:
Re-reading the thread, the *right* solution is to fix while-no-input,
and apparently the easiest way to do that would be to change
while-no-input so that it calls an `internal--adjust-polling-frequency`
function after binding throw-on-input (and maybe after un-binding it as
well).
On systems which don't use polling at all,
internal--adjust-polling-frequency would just do nothing.
The patch should be fairly simple, but I don't think anyone wrote
such a patch yet, so I can't tell if it would be appropriate for emacs-25.
Maybe for emacs-25 we can live with the workaround of adding a "dummy"
call to (input-pending-p) in execute-extended-command--shorter.
