My suggestion here is that you can rely on HTTP 1.1 cache control
semantics.  Specifically, HTTP 1.1 allows pages to define a
refresh/expiration time.  It also allows them to specify they they
should not be cached at all.  My point is that a page that does not expire
before the computation outside the IOMonad completes should be ok.

I suppose it would be really elegant if we could define a new net monad(?)
which allows us to reason generally about computations with different
expiration times, but that goes far beyond my expertise.
