Process I/O packets in batches. If a batch is processed and there are still packets pending, send a signal locally to the packet handler and return to the entrypoint signal dispatcher. This prevents clients from starving each other, which happens when a client continuously submits packets at a faster rate than the server can process. Fix #2900
