I wonder if the problem is just that `input-pending-p' does not
respect `while-no-input-ignore-events'? `while-no-input' actually uses
`input-pending-p' before it even attempts to run the body:

          (setq val (or (input-pending-p)
                 (progn ,@body)))

I think that `readable_events' needs to be modified to do exactly what
`kbd_buffer_store_buffered_event' does with regard to ignoring events
if `READABLE_EVENTS_FILTER_EVENTS' is set.

I have no idea why `USE_TOOLKIT_SCROLL_BARS' is considered when
determining whether or not to require `READABLE_EVENTS_FILTER_EVENTS'
when filtering out the focus events. I imagine that that focus event
filtering could be replaced with a check against
`while-no-input-ignore-events'

Does that make sense?
