I have a bigger reply coming; however, I should note that this is basically
what web2 did with its IStream interface. While this has a big advantage over
the status quo (i.e. "not solving the problem") the _way_ it solved the problem
ended up being both (A) error prone, and (B) slow. It's the sort of slowness
that PyPy doesn't even help mitigate, because all the callbacks are
heap-allocated, and... to be honest I don't even fully understand it, but I
have experimentally verified that it's still pretty slow :-).
This is more or less the reason that Tubes exists, although more on how we
might proceed either with or without tube in another message...
