Yes, the 'poll' approach apparently works stable and does not cause any
measurable performance decrease. But it would need some carefull
cleanup/review, especially WRT locking. Now that all real event handling
work is happening in the poll function, it still has to be protected
against the (potentially also long-running) reset function which in
current design can be called e.g. from a different thread due to tx
timeout, and this does not look good, but it is a bit beyond my
capability to arrange it better. Besides, the idea was to keep the fix
simple and avoid a massive rework...
Thank you,
Regards,
Nikolai
