(not to disagree, just wondering out loud.) these kinds of bugs always
make me wonder if they are there and hard because the design isn't
helping as much as it should. when i hear "race condition" i think
"gosh why aren't we all using dataflow?" for example, not that it
might have any bearing on this particular case. (of course the
dataflow core would have to be bug free ha ha.)

i thought the issue was an actual bug, not a design choice?
