The latter, parellel requests, and then join the results when they all
come back. I've come up with some bastardization of MapReduce now, but
this would be a lot nicer if Emacs had something like
https://github.com/chuntaro/emacs-promise built in, so I can combine
it with a generator to emulate async/await semantics.
