While the oom is the only current kernel user of MMF_UNSTABLE (in a
sense it sets the flag) the flag should denote that any page faults are
reliable because it might fault in a fresh memory and user would lose
the previous content without knowing that. Not sure MMF_OOM_REAPING
would reflect that reality better.
