Well, as Mr. Spock would say,
Fascinating!
It appears that the combination of a shell pipeline and
fifos makes the implementation of a multi-streamed pipeline
possible. The problem is the lack of "stages",
especially the stream splitting and stream joining ones.
Thank you, Bob and Boyd, for your insights and expertise.
