Actually, it's supposed to do exactly that. stream_demux is for 
asynchronous demuxing afterall.
Waiting is not possible without introducing dead locks. Besides, if you 
want to wait, then you are better off with a synchronous child demux; 
stream_demux is counter-productive.

But that's besides the point: the patch does not solve that problem 
either way.
