No.  These are not the issues we discussed.  The acceptable regression
is the invlpg~shadow test case only.


These leak check failures are because the XSA-195 PoC is somehow causing
qemu to segfault.  I cant explain why, because qemu should be involved
at all, and it is especially suspicious that it is only older branches
where this happens.
