Will,

I have checked the new Sashiko finding against this v11.

To approach its claimed 35-trillion bound, every L1 descriptor,
STE and CD L1 descriptor must pass the validations, which takes
a deliberately built aliasing table but is not likely reachable
in practice: with a corrupted memory, one of the entries would
more likely either skip the iteration (V=0) or fail the test.

I tend to ignore that. But if you think it is worth addressing
and have some good idea about it, I don't mind a respin.

Thanks
Nicolin
