No, there is no direct relationship between the number of
calls to DomainEventRegister* and AddHandleFunc. In the
current impl we only call AddHandleFunc once per virConnect
object, but again that isn't guarenteed - different libvirt
drivers will invoke AddHandleFunc / AddTimeoutFunc a different
number of times, as is most suitable for their precise needs.
