Thank you.

I observe that Daniel Berrange also wrote a libxl patch to solve this
problem.

I read the interdiff and the only difference is that Anthony's patch
changes the internal function name to qmp_parse_query_cpus_fast
whereas Daniel's doesn't.

This gives me a fairly high confidence in the patch :-).
