Not sure I follow. Is there another thread where somebody worked out why
this 62meg limit was happening?

Note that I sent v2/v3, to fix the original problem in a different way,
and if that looks good to the QEMU maintainers, then we can all be happy
with that. But I *haven't* addressed and still don't fully understand
why the 62meg limit applied to my v1 in the way it does. Did you find a
bug there to fix? If so, please do CC me.
