Why do we need to write the pickled data into a slot?  We have no further need
fro it (after doing the send) I think. Why do we need to hold on to it?

Done.

+
+  // Send the sequence number and list of pickled tracking data over synchronous
+  // IPC, so we can clear pickled_tracking_data_ afterwards.
+  RenderThread::Get()->Send(new ChromeViewHostMsg_RendererTrackedData(
+      sequence_number, pickled_tracking_data_));
+}
