Yes - I was thinking the same.  I suggest that when xen-4.2-testing.hg
gets branched off unstable, this debugging gets put back to just being
an assert as before.  However, I am quite unsure as to what would happen
with interrupts following that failed assert.

I shall re-do the patch.  I think it is a fairly sensible patch to have
in even after the main debugging has been removed, especially if similar
debugging needs to be done in the future.
