fix awful event re-propagation between every part and parent and part

fix awful event re-propagation between every part and parent and part
and.... u get the idea. this made an n^m list of messages... where n
was 3 of messages sent and m was # of child parts (42 of them)... this
caused a silly 3 of timers to be allocated... don't ask how many. in a
simple snapshot i saw 101mb of timers allocated... and i was just
starting... anyway - this makes the propagatiopn not propagate down
and then back up again... and it only needs 1 timer allocated to
handle a re-schedule of processing messages. not N. "leak" that was
just a massive memory spike) is now fixed.
