max number of applications

It would be nice to have a way to limit the maximum number of applications with a given name.

    <application name="mcstas_server" stream="yes" max_applications="10"  restart="no" starting_time="0" retries="0" stopping_time="1" log_directory="default" >
                  <start executable="/tmp/devel/bin/mcstas_server" args="-d /dev/shm/panosc/prod/"/>
                </application>
