25939	Remove transaction from QuerySet.update_or_create's save()	Tim Graham	nobody	"According to Aymeric on [https://github.com/django/django/pull/5804 the pull request]:

It will have beneficial performance effects if:
* `ATOMIC_REQUESTS` is not in use
* `update_or_create` ends up creating an object
* the `save` method of that objects does long things like sending email after the write (i.e. once it holds an exclusive lock on the database)
