/**
 * This file is a cron microclock script.
 * It will be used as replacement of setting individual
 * cron lines for all virtual instances.
 *
 * Setup this vcron to run at the smallest period possible, as
 * it will schedule all availables vmoodle to be run as required.
 * Note that one activaton of this cron may not always run real crons
 * or may be run more than one cron.
 *
 * If used on a big system with clustering, ensure hostnames are adressed
 * at the load balancer entry and not on physical hosts. Thus the cluster
 * settings of vmoodle will NOT be applicable to the web operated vcron (this script) as
 * the load balancer itself diverts the cron http processes.
