I think it=E2=80=99s a good idea!
I wonder what the UI will look like: (guix status) would no longer
display a progress bar when there=E2=80=99s more than on job (build or down=
load)
taking place at the same time.

Note that not all builtins are downloads. Fixed-output derivations are
(usually) also downloads.

We should also allow =E2=80=98set-build-options=E2=80=99 to set this option=

We=E2=80=99d need to update doc/guix.texi.
It would be great if you could test this patch for your daily usage. I
find it surprisingly easy to break things in the daemon. :-)

Hi guix!
This patch allows to count builds and downloads separately. The idea is
that downloads need bandwidth, but no CPU, while builds do not need
bandwidth, but need CPU. With this patch, guix will be able to download
substitutes while building unrelated packages. Currently, guix needs to
wait for the download to finish before proceeding to the build. This
should reduce the time of guix commands that need to build and download
things at the same time.
What do you think?
