The code looks good, but there are some cases that are not handled:

1. The sink goes away while the passthrough stream is running. Should be
possible to add a sink unlink hook that runs before
module-rescue-streams and restores sink-inputs to the sink.

2. The passthrough sink input is moved. Just need to hook up to the sink
input MOVE_FINISH hook and treat it the same way as sink input unlink.

I think that should be it.
