     * In a single threaded environment we could walk down the hierarchy,
     * aborting any actions which are no longer valid, and creating any new
     * ones. However, in a multi-threaded environment, a thread can make a
     * call from any point in the client's hierarchy, and multiple client
     * threads can invoke the same server object. So, in general we cannot do
     * this optimisation. We must maintain the entire tree until portions of
     * it have explicitly been termined.
     *
     * Once we find the point in the new hierarchy which deviates from our
     * current representation, we begin to assemble a new subtree in much the
     * same way as we did for creating a completely new hierarchy.
