-def doctest_reload():
-    """Properly reload doctest to reuse it interactively.
-
-    This routine:
-
-      - imports doctest but does NOT reload it (see below).
-
-      - resets its global 'master' attribute to None, so that multiple uses of
-        the module interactively don't produce cumulative reports.
-
-      - Monkeypatches its core test runner method to protect it from IPython's
-        modified displayhook.  Doctest expects the default displayhook behavior
-        deep down, so our modification breaks it completely.  For this reason, a
-        hard monkeypatch seems like a reasonable solution rather than asking
-        users to manually use a different doctest runner when under IPython.
-
-    Notes
-    -----
-    
-    As of Python 2.6.6, 2.7.1 and 3.2, this monkeypatching is no longer required.
-    doctest now takes care of resetting sys.displayhook itself. This function
-    remains for now in case anyone has to work with older versions, but it's
-    no longer called during IPython startup.
-
-    This function *used to* reload doctest, but this has been disabled because
-    reloading doctest unconditionally can cause massive breakage of other
-    doctest-dependent modules already in memory, such as those for IPython's
-    own testing system.  The name wasn't changed to avoid breaking people's
-    code, but the reload call isn't actually made anymore."""
