+ * The Sequential operation does a heartbeat request to each PDP one at a time. This has the flaw
+ * that any PDPs that do not respond will hold up the entire heartbeat sequence until they timeout.
+ * If there are a lot of non-responsive PDPs and the timeout is large-ish (the default is 20

-     * Heartbeat thread - periodically check on PDPs' status

-     * Heartbeat with all known PDPs.
-     * <p>
-     * Implementation note:
-     * <p>
-     * The PDPs are contacted Sequentially, not in Parallel.
-     * <p>
-     * If we did this in parallel using multiple threads we would simultaneously use
-     * - 1 thread and
-     * - 1 connection
-     * for EACH PDP.
-     * This could become a resource problem since we already use multiple threads and connections for updating the PDPs
-     * when user changes occur.
-     * Using separate threads can also make it tricky dealing with timeouts on PDPs that are non-responsive.
-     * <p>
-     * The Sequential operation does a heartbeat request to each PDP one at a time.
-     * This has the flaw that any PDPs that do not respond will hold up the entire heartbeat sequence until they
-     * timeout.
-     * If there are a lot of non-responsive PDPs and the timeout is large-ish (the default is 20 seconds)
-     * it could take a long time to cycle through all of the PDPs.
-     * That means that this may not notice a PDP being down in a predictable time.
