That sounds interesting.  Are you saying that you not only see hangs with
my code but you also see hangs with the old code (in the only case I've
heard of where someone had trouble with my version of the above code,
that smeone also said that reverting my change fixed his problem).
Maybe instead of discard-input we could do something like

      (while (input-pending-p)
        (push (read-event) w3-temp-read-events))

and then push those events back onto unread-command-events when the whole
thing is done ?

Still, it seems the problem is revealing a bug in the underlying C code,
and it would be even better to fix that one.
