If you throw a load of handles at it, it'll probably push all the
older handles out, but you'll still be left with a load of handles
knocking around.

I'd appreciate if this collectgarbage thing was official too (I also
dislike having to edit the v8 Source).

This was mentioned in that other thread:

Which I expect would have the exact same effect as CollectAllGarbage..
(it just feels wrong to be calling a js function to do this).
