A good thing to keep in mind, but for the short term I'm not sure
we need it; the proposed new contexts are all for indefinite-lifetime
caches, so there's no chance to make them go away automatically.
Eventually we might have more uses for limited-lifetime contexts,
though.
Something else that needs to be looked at is how memory contexts
are tied to "portals" presently. That mechanism probably needs
to be redesigned. I have to admit I don't understand what it's
for...
