RE: The Death of Finalizers

Do we still have atomicModifyIORef?

I don't know that there's that much point now that Haskell finalizers are gone. I don't have a strong objection (esp. since it seems every implementation now has it) but it doesn't seem so necessary now.

It ought to be significantly faster than using MVars if you can get away with it. I haven't measured it though. Cheers, Simon
