Pasting a large amount of data into a console does not spin the
cpu up to 100% utilization.  That portion of the fix is, in fact,
correct.

However, none of the data appears, and i cannot ^] my way out of
the console.  any active ssh sessions become non-responsive.

When i 'xm destroy' the domu, the data i pasted appears on the
dom0's ssh session.  (i'm ssh'd into the dom0, and execute the
console from there)
