Ogg tries to index the stream endlessly, which obviously eats your mem
and takes forever, since it has no end.

As for asf, it's probably something similarly braindead. The solution is
to introduce a new is_network_stream tag or so and use that (instead of
is_stream) to decide whether to index or not. A hack for now is to set
is_stream to 1 and not index in ogg for network streams, but that breaks
seeking.
