The point of the scheduler it that for every worker it runs one task at the time. tasks are queued and picked up by worker. Each worker picks up a task, and when completed (or failed) posts results, if necessary queues new tasks, thank picks up the next task.
This is different from cron. cron always start tasks at scheduled times even if other tasks are in execution. The cron model has the problem that withut a limit to the number of concurrent tasks you can easily run out of memory.
