The "normal" cached tree, under some circumstances, will return a cached
value from the latest access to that particular node.
However, as Michael did not read .../temperature but ../humidity, there
should be no cached value for the temperature node. (Well, in reality,
it is, because reading .../humidity in fact reads .../temperature
internally and *does not* bypass the cache. Good riddance.)
But it's better not to rely on the cache.
