IMO, draining only makes sense on single ES. Furthermore, draining is only 
meaningful in contrast to flushing. In stream output, you can assume that an 
ES is being drained when it gets deleted. So there is really no point in 
adding explicit draining, AFAICT.

And then, the generic problem of deadlock muxers can only be fixed by passing 
the PCR to the stream output - which is far more powerful and generic than 
draining.
