.. warning::
Currently there is a size limit (not applicable for ``sqlite``) that the
``results`` will contain. This size limit will restrict how many prior
failures a retry atom can contain. More information and a future fix
will be posted to bug `1416088`_ (for the meantime try to ensure that
your retry units history does not grow beyond ~80 prior results).
