Another glitch. If the source is from the cache, we can't trust that elements
of base or add allocated will still in memory when the cache is called :( Not
unless we also discard all decendants when we refresh the cache. This implies
that we need a protected refcount for each of the cached elements, not only by
the request that is relying on the data, but the straight down the chain.
