Comment (by Adam (Chainz) Johnson):

 Dan, I think you missed a step here... @thomazzo is talking about when
 Django clones test database for parallel runs, which is done at the start
 of test runs by `setup_databases`:
 https://github.com/django/django/blob/master/django/test/utils.py#L176 .
 This calls through to backend specific functions, which Django has for
 MySQL here:
 
https://github.com/django/django/blob/9a88c6dd6aa84a1b35e585faa0058a0996cc7ed7/django/db/backends/mysql/creation.py#L31

 I think the request is really around passing `--routines` to `mysqldump`
 in `_clone_db`. I think this is a good idea and probably just needs one
 line in that function.

 Dan, you could make a test case from your example repo by using the
 `CREATE FUNCTION` statement in a `RunSQL` in a migration.
