My guess is that people do have this problem, they just don't know
where that memory has gone. I know I don't count objects unless I have
a process that's leaking memory or it grows so big that I notice (by
swapping or chance).

That said, I've never noticed this particular issue.. but I deal with
mostly strings. I have had issues with the allocator a few times that
I had to work around, but not this sort of issue.
