With ``FLOGTOTWISTED=1``, sufficiently-important log events will be written
into ``_trial_temp/test.log``, which may give you more ideas about why the

+``level=OPERATIONAL`` threshold. You can change the threshold via the ``FLOGLEVEL``
+variable, e.g.::

+(The level numbers are listed in src/allmydata/util/log.py.)

+To look at the detailed foolscap logging messages, run the tests like this::
