For a known environment, it would behave the same regardless of r(t) for all t > T.

Matt, I think the basic problem here is using an unbounded utility
function. Since you'll get infinite expected utilities, there's no way
to choose between actions. You'd have this problem whether or not you
believe in immortality, as long as your utility function is unbounded.
