+ <listitem><para>Configures the time to

+ finish. If a command does not exit

+ will be considered failed and be shut
+ down again. All commands still running
+ will be terminated forcibly via
+ <constant>SIGTERM</constant>, and after another delay of

+ Takes a unit-less value in seconds, or

+ manager configuration file
