 // - Send a serverlist with faulty ip:port addresses (port > 2^16, etc).

 // - Test pinging
-// - Test against a non-LB server. That server should return UNIMPLEMENTED and

 // - Random LB server closing the stream unexpectedly.
 // - Test using DNS-resolvable names (localhost?)

+// Findings from end to end testing to be covered here:
+// - Handling of LB servers restart, including reconnection after backing-off
+//   retries.
+// - Destruction of load balanced channel (and therefore of grpclb instance)
+//   while:
+//   1) the internal LB call is still active. This should work by virtue
+//   of the weak reference the LB call holds. The call should be terminated as
+//   part of the grpclb shutdown process.
+//   2) the retry timer is active. Again, the weak reference it holds should
+//   prevent a premature call to \a glb_destroy.
+// - Restart of backend servers with no changes to serverlist. This exercises
+//   the RR handover mechanism.
