In any case, I think it's OK to explicitly set those fields to nil.
For objects that can be killed (and not revived) like frames, terminals,
processes, it's OK to zero out (some of) their fields to make sure that
even if someone holds on to them, what they referred to can be GC'd (as
long as it makes no other visible difference: e.g. frame parameters
should be nil'd).
