I think my main thought would be to try and domore of the event dispatch work in the python layer, rather than C layer. So rather than doing the de-multiplexing to all registered callbacks in libvirt_virConnectDomainEventCallback, have that C method call into a python virConnectDomainEventCallback function, and have that de-multiplex the events out to all application callbacks. I think it'd probably make the code a little easier to follow, and might simplify the ref counting problems. Likewise I think I'd also keep more of the 'DomainEventRegister' and 'Unregister' impl in the python layer. Perhaps keeping the list of callbacks as an attribute in the 'class virConnect', rather than the static global variable pyobj_domain_event_cbs.
