Your idea can be combined with the maxint/2 initial refcount for

non-disposable objects, which should about eliminate thread-count updates for them. --

I don't really like the maxint/2 idea because it requires us to differentiate between globals and everything else. Plus, it's a hack. I'd like a more elegant solution if possible.

It's not really a solution either. If your program runs for a couple minutes and then exits, maybe it won't trigger some catastrophic behavior from this hack, but if you have a long running process then you're almost certain to be screwed over by this (it wouldn't even have to be very long running - a month or two could do it on a 32bit platform).
