Thanks for your advice. The performance impact of doing 1 extra hypercall for 'availheap' is completely irrelevant in this context. The time for 1 extra hypercall is dwarfed (by several orders of magnitude) by the overhead due to 'xm' and 'xend' being in python & using XML-RPC. We should just use the existing hypercall & not worry about time overhead we'll never notice.
