You absolutely do _not_ want to manage memory in 16kB chunks (or 64kB for

AFAIK at least for user visible anonymous memory Windows uses 64k
chunks. At least that is what Cygwin's mmap exposes. I don't know
if it does the same for disk cache.
I think that's just the region address and size granularity (as in
vmas). For paging they still use the mmu page size.
