Isn't the point of mmap() to just directly access a file as if it were memory? I can see how it would fool the reporting tools into thinking that much memory was in use since it is part of your virtual address space, but I am not following why it would actually *use* more memory. Perhaps it is overwhelming the buffer cache and that is pushing other data pages out to swap? Just a wild-assed guess here.
