That was a really confusing description in hindsight...
Consider it this way: what you're changing could easily be written as a
custom reduce function in JavaScript. The only difference between the two is
that one is in Erlang and there's some goop about aliasing the implementation
with a "_name". That's it.
And given that we know that reduce functions can return whatever they want
we know that there's no reason that we have to change anything related to
chttpd or fabric or invent changes to the worker protocol that's sending
messages around.
