    // 1. When doing a sync call, other D-Bus messages may have arrived, waiting in the read queue.
    // In case an event loop is inside a poll in another thread, or an external event loop polls in the
    // same thread but as an unrelated event source, then we need to wake up the poll explicitly so the
    // event loop 1. processes all messages in the read queue, 2. updates poll timeout before next poll.
    // 2. Additionally, when sending out messages, these may be too long to be sent out entirely within
    // the single sd_bus_send() or sd_bus_call_async() call, in which case they are queued in the write
    // queue. We need to wake up the event loop to continue sending the message until it's fully sent.
