Just curious, but couldn't one load a process with the data section shared
and copy-on-write the instant a program is loaded? Isn't it true that the
data section can be paged out of the executable file until it is written to?
(Zero-filled pages are initially shared anyhow.)
I'm a little surprised that Linux doesn't do this, or does it? And if not,
would doing it get some of the benefits of mergemem without the runtime
overhead?
