It isn't spinning.  It is called via update-rc.d from several postinst
scripts, and report the problem every time.  There is no way to know
where to sensible break the cycle, so it was decided early to reject
installation of packages introducing a cycle, to force people to address
the issue right away while the machine is still running instead of
risking a non-booting system to surprise the user on the next boot.

The initial report just show a lot of packages being installed, not a
loop.

Sure, one could try to break the cycle, but the end result might be to
brick the machine.

Could this be caused by a removed but non-purged package with an broken
init.d script?  I've seen quite a few of those.
