I don't know for sure, but I guess that resources associated with a file descriptor are freed when all references to the descriptor is released. If you mmap a file descriptor and close it, that close is at the moment almost no-op (except it decrements a kernel internal counter by one), and the resources associated with it will be released when you munmap, no?
