Multics used. Seems like a perfect match to me.
Hence my question regarding the number of rings used by Multics. Just
because there's multiple contexts doesn't mean that there's _enough_ of
them. From multicians.org:
Although there were 64 rings
(an illusion created by software) on
GE 645 Multics, there are 8 rings, supported in hardware, on the
Honeywell 6180 in its various models.
