Revisiting this.  The problem can only happen on OOM situations, so it's
not that likely to hit in real life; but we should indeed fix our code.
 I think the easiest way is to fix remoteDomainEventQueue to gracefully
do nothing on a NULL event (events are best effort, and if OOM occurs,
skipping event delivery is an acceptable action, since we have no way of
reporting the error).  I'll post a patch.
