But is it easier to scrub memory manually before freeing, or just make
a hypercall telling Xen to put zeroed pages there?
I think Steven's right... we may be introducing subtle latent bugs;
overall it doesn't sound like the benefit is worth the extra
complexity.
Steven, if we can make the PV drivers do something sensible wrt failed
writes during a crash, that might be the best solution.
