My earlier patch aimed to allow WALReceiver to wait on both a latch and a
socket as well as allow WALWriter to be active, so that WALReceiver could
reply more quickly and handle greater workload. As I explained previously
when we discussed that in recent posts, it is necessary infrastructure to
have anybody wait on anything higher than remote-fsync. I aim to complete
that by 1 Jan.
