I'd say make it configurable.

on-persistent-overload=abort/err/ok/unknown

to represent all three possible states.

But that is based on the assumption that unknown is "outcome is not
known" and that Squid then skips the access rule and looks at next
rule. Have not looked in detail in how current Squid operated with
these conditions.

Starting with only abort/err is good. err should then map to the same
as a negative helper response which is the most clear buldingblock to
work with then bulding access lists.

It does not make sense that err in this context should map to different
logics depending on the directive.
