If we end up reading all pending X events in the course of other server execution, then our notify FD callback won't get invoked and we won't process them. Fix this by noting that there are queued events in the block handler, setting the poll timeout to zero and queuing a work proc to clear the event queue. v2: use a work proc to clear the event queue rather than doing it in the block handler directly.
