I think that this would mean having essentially one file per package,
which in turns would add a lot of I/O overhead.

More importantly, the problems we are facing here have nothing to do
with circular dependencies.  The main issue remains
<http://bugs.gnu.org/15602>.

The next issue would be multi-threaded compilation, which I think may be
fragile due to unsynchronized accesses to module objects and obarrays,
as discussed in this thread.

WDYT?

I would be happy to see more eyeballs looking into it!  :-)
