This is more readable than comma-space delimiters. I mainly care that we
support Python list form in the config file though.

I think Ian's right that setting the same cpumask for all VCPUs ought to be
the most common operation: Xen ought to do something sensible with that (it
probably already does with the new scheduler). So fixing the *existing*
syntax to do the sensible domain-wide thing, if it doesn't already, would be
nice.
