Yes.  A nice feature of counting calls to libxl__ao_cancellable_register
is that it is closely tied to identifiable points in the lifetime
of the cancellable operation.   However for better resolution we could count
event-loop iterations since a registration call, or any other easily
identifiable point.

Thanks,
