OK. At least now we now know that the two designs differ in this aspect.
It is still not clear to me why both of you are using the term
"pump" (especially a bidirectional one!) when describing what is,
apparently, a "pipe", but that should become clear once Amos moves from
blobs to descriptions and examples.

I did not realize you plan to "re-integrate back into Squid2 codebase"
as opposed to the latest Squid code. Glad this is clarified!
Approximately when do you think this re-integration into Squid2 will
happen?

Thank you,
