There are two events involved in both functions ("event" and "event2")
and we can send event2 only if event is not NULL, which is the reason
for
if (event) {
qemuDomainEventQueue(driver, event);
qemuDomainEventQueue(driver, event2);
}
It would be possible to rewrite it as
qemuDomainEventQueue(driver, event);
if (event)
qemuDomainEventQueue(driver, event2);
but I think the original version is slightly better.

Yeah, both came in after I originally created this patch. I will clean
them before pushing.
