to do prefetch on either a lazy or eager basis. Lazy means that the prefetch does not occur until and unless the client actually makes a get_var request. Also repaired a problem where doing prefetch wrt a url that has a constraint will prefetch a whole variable if its constrained size is small enough, even if the underlying variable is too large to warrant prefetch.
