Hmm, that's new to me, but certainly very useful and would do the trick
in the case of X.

The only problem seems to be that it doesn't seem to be shareable across
fork() and that is isn't easily tunable after a process is started.

Btw.: Why is this in madvise() and not in rfork() ? Is it because of
POSIX ? Any pointers are welcome...
