That's why mmap is for. Using read is just stupid.
I've been told mmap hugely complicates virtual memory systems.
Anyone want to confirm or deny this?
Yes, it does. Hugely. But, on the other hand, it's the entire basis
of modern malloc implementatons and dynamic linking and loading.
I can see dynamic linking needing to load from file on fault, but
malloc puzzles me. I wonder if it is the way it is just because that's
a good way to make it fit with the page-fault-loading of dynamic
linking and mmap.
