Yes, there's a better way: don't use read_write_dispatch, but instead
write a proper main-loop around select(2) or poll(2). You'll have to
handle the timers and file descriptors yourself. You'll avoid a
500-millisecond timeout and you'll save battery resources more. And you
won't have a 500-millisecond reaction time to cancelling the loop.

Yes, that's supposed to work.
Note that the unref() does not lead to a disconnect.
