That may be. I don't know enough about the specific issues you raise
below to comment. But Ingo wasn't bringing up those issues: he was
disagreeing with the whole idea of including dom0 Linux as a key
component of the Xen system. If the Xen project were to start over
from scratch, we might make a lot of different decisions; but running
Linux as the hypervisor (as KVM does) or forking Linux (as Ingo seemed
to suggest) are not among them.
