Could you please elaborate on "permanent"? To what structure the
information is currently attached, and what, if anything, can make
that structure "go away", short of a reboot?
Of course, we could MADV_NORMAL afterwards, though that would
require changing more than one character. I'm not sure I'm ready for
so much coding... :-)
