14050	Signals for transaction commit/rollback	Ask Solem <ask@…>	nobody	"Some users of django-celery have the problem of publishing references to
database state that has not yet been commited.

E.g:

    def add_user(request):
        user = User.objects.create(...)
        # Import the users address book contacts
        import_contacts.delay(user.pk)


The proposed solution is to add a way to delay these calls until the transaction is committed:

    from djcelery import on_transaction_commit

    def add_user(request):
        user = User.objects.create(...)
        on_transaction_commit(import_contacts.delay, user.pk)

This doesn't seem very easy to accomplish, as I can't see any mechanism
to hook into commit/rollback. Do you think it could be possible
to add new signals for this?
