Now that I think about it, there are a few places (including this cycle)
where modules import other modules only for the side-effects of having
something registered; e.g. pypy.annotation.model imports
pypy.annotation.unaryop and pypy.annotation.binaryop, and
pypy.rpython.rtyper imports many of the pypy.rpython.r* modules.  There
is the same problem with every place that uses the extregistry
(currently only rctypes and some ootypesystem functions and types).

Maybe we could reorganize that by moving the necessary import statements
to the __init__ of the appropriate packages.  It certainly looks clearer
and easier to control than these import loops.

(It would also require us to finally do the long-pending clean-up of
dividing the 'rpython' package in two: one for the rtyper and one for
the modules of stuff that RPython programs are allowed to call, e.g.
rarithmetic and objectmodel.)

A bientot,
