   - the InvalidTarget checks seem like they're generic preconditions
     that all drivers would want enforced
 
+  - _safe_log() logs sanitized message data
+
+  - unique_id used to reject duplicate messages
+
+  - local.store.context used by common logging - basically, how to make
+    sure the context of the currently dispatching rpc is available to
+    logging. Need to abstract out the dependency on eventlet for this.

+  - the current rpc code dispatches each method in its own greenlet,
+    we need to do the same in the eventlet executor
+
+  - I'm not sure listener.done() is really needed - can't we ack the
+    message before returning it from poll() ?

 Things I don't like:
 
   - CallContext - we already abuse the term "context" enough
