I believe that this decision -whether we dispatch, block o completely
change the approach- has to be taken as part of this bug. We would need to
further investigate, particularly on the SequencedEvent clients side.

Discarding non-SequencedEvent events or holding them for the future is a
trivial change. In fact, I tried it some days ago before proposing the
latest version of the patch. What I noticed in your test at [1] was: events
were injected at a high rate, the SequencedEvent.list list steadily grew,
the EDT was very busy dispatching them -"blocked" like- and there was no
room for dispatching other events keeping the GUI unresponsive -they were
rejected by the waiting filter-. If I remember correctly, repainting after
changing the counter was affected by this.

Regards,
Martin.-
