A source the renderer pulls samples from can be held between any two frames,
because the renderer decides when each one is drawn. A source that presents
its own frames owns the playhead, so holding it means stopping the producer
and starting it again, and a gate that stops one has to bound its own wait
or a producer nothing answers for never runs again.
