I gave a look to your patchset and this is yet another case in which the
only way to truly control the allocation/release behavior at low level
(without intrusive approaches) is to -indeed- use a page flag.

If this gets merged I would like to ask Andrew and Christopher to look
at my recent memory sanitization patches. It seems the opinion about
adding new page flags isn't the same for everyone here.
