Django-celery-transactions holds on to Celery tasks until the current database transaction is committed, avoiding potential race conditions as described in Celery's user guide.

Features:
* If the transaction is rolled back, the tasks are discarded. Django's
transaction middleware does this if an exception is raised.
* If transactions aren't being managed, tasks are sent as normal. This means
that sending tasks from within Django's shell will work as expected, as
will the various transaction decorators commit_manually, commit_on_success,
etc.
