This is so important if you want to avoid incredibly gnarly race conditions. In particular for us: jobs being run even before the transaction has been fully committed to the database.
We utilise a decorator for our job addition to external queues, such that the function that does the addition gets attached to Django's "on transaction commit" signal and thus don't actually get run until the outer database transaction for that request has been committed.
