Thank you, as always, for your feedback.

Yep, it is absolutely thread unsafe. However, because an unref on a
GValue could cause an unref on a GUI object, it must be done from the
GUI thread. Thus, this operation may *only* be done from one thread.

Am wondering how you suggest we avoid it. I mean, we could do our own
hashtable impl, but ick, I would rather write a few lines of C. And
given that we not only have to wait for Mono's generics but also for MS
to release theirs and for it to become widely used enough that people
upgrade, that may be quite a long wait.
