I agree that the case you describe is a concern, but I don't
see that we have a choice at this point. I would like to get
this free with the queue thing and fixing up of the Notifier
done, and then worry about overhauling the ref counting approach.
We need to get these changes finished off and merged back into
the HEAD very soon. Currently, we have no thread safe code to
point people to. Something that works for 99.999% of the cases
is better than something that works for 0% of them.
