Yes, this is what happens now. A demux is chained via stream_Demux. The 
demux does implement the demux interface as any other demux and returns 
0 (VLC_DEMUXER_EOF) from pf_demux() because it ran into an eof condition 
- but this eof is in fact a stream eof not a transport eof. The same 
transport may send another stream without interruption now.

This will cause the access_demux to eat all system memory. Shouldn't we 
have a way out there?
