Dpkg doesn't handle them "correctly". It breaks the cycle arbitrarily,
except it prefers packages without postinstall scripts. This may be
adequate for most (mis-)uses of circular dependencies, but it's not
"correct". Hmmm, "correct" is probably not the right word to use here,
since there is no "correct" answer, per se. "Reproducibly" is what I
mean.
