DDD - the rule that Entities can't access Repositories directly
...filter order from tbl_order where placed_at is less than 30 minutes before sysdate" (see this answer).

t = ThreadWithExc( .....
Understanding NSRunLoop
... will then return to its loop, processing input from various sources, and "sleeping" if there is no work to do.
That's a pretty high level description (trying to avoid too many details).
