+
+    * Ensure that as many DEBUG messages as possible are actually

+       often have not been).
+
+    * Ensure that we create useful output for tests that doesn't

+      100 MB of debug logging on every run).
+
+    To do this we create a logger fixture at the root level, which
+    defaults to INFO and create a Null Logger at DEBUG which lets
+    us execute log messages at DEBUG but not keep the output.
+
+    To support local debugging OS_DEBUG=True can be set in the
+    environment, which will print out the full debug logging.
+
+    There are also a set of overrides for particularly verbose
