This module provides an interface to detach the queue execution from cron. Provide a Drush command "drush meq"(drush mob-exe-queue) to execute the selected queue takes that were excluded from Cron. It is useful for a large site which has over a hundred of thousand of tasks in the queue, cron is not able to finish all the tasks in time. If you want to free cron from some huge queue job, and let a dedicated process take care of the queue, this module is the one. Drush have command to execute the queued task, but can not stop cron from executing the queued task.
