+=head2 only_namespace
+
+Action command from the user can be an action name or the action name plus one
+child namespace in the form: "C<action::child>". This slot stores the C<child>
+component of the command so that C<action> is backwards compatible with
+Netdisco.

+=head2 job_priority
+
+When selecting jobs from the database, some types of job are higher priority -
+usually those submitted in the web interface by a user, and those making
+changes (writing to) the device. This slot stores a number which is the
+priority of the job and is used by L<MCE> when managing its job queue.

-failed to connect, should increment defer counters
