The crashes are fixed in unstable, but pools still do not work in xen-unstable
unless the system is booted with the arinc653 scheduler, the dom0_max_vcpus
parameter is set to 1, and cpu0 is never removed from Pool-0.

I have pools working locally without these restrictions, but I was unable to get
a patchset around before the feature freeze was declared, so I believe it is too
late to try and get it into unstable.  (George, correct me if I am wrong.)

However, I am more than happy to provide Simon with my patches to get arinc653
cpu-pools completely working with the understanding that they may change before
they make it into xen-unstable.

Also, the arinc653 scheduler currently only supports a scheduling resolution of
1ms, but it is a trivial task to change it some other resolution.
