I'm not deep enough in UNIX to know, and I'm not sure oranges and bananas
compare, but it sounds like 'streamstate all' is where you look.
It's mostly useful to write stages that behave differently when some
streams are not connected (but it's just a matter of time before I regret
such design).
Even more subtle is when you act on relative timing differences between
streams (like arrival of a new key on the secondary of a cipher stage). I
don't see an analogy with buffered streams.
