Dima Dorfman af13e3abb9 Unimplement panic(8) by making sure that we don't recurse into a
ruleset.  If we do, that means there's a ruleset loop (10 includes 20
include 30 includes 10), which will quickly cause a double fault due
to stack overflow (since "include" is implemented by recursion).
(Previously, we only checked that X didn't include X.)
