If you use mmap for your allocator then beancounter will get it right. Every
resource knows which beancounter it was charged too. It adds an overhead the
average desktop user won't like but which is pretty much essential to do real
mainframe world operation. So it would become

        mmap(buffer in pages)

With lightwait counting semantics its hard to make any tracking system work
well in the corner cases like resources that survive process death.
