+# Ghost messages are difficult to test since they're nearly invisible.
+# However, if the upgrade works correctly, the ghost message should
+# retain the right thread ID even if all of the original messages in
+# the thread are deleted.  That's what we test.  This won't detect if
+# the upgrade just plain didn't happen, but it should detect if
+# something went wrong.
