Comment (by Simon Charette):

 > Do we really want to iterate over connections? As far as I'm aware, this
 will force initialization of all database connections

 I know it's confusing (I had to check myself to make sure when accepting
 the ticket) but `connections.__iter__`
 
[https://github.com/django/django/blob/9a27c76021f934201cccf12215514a3091325ec8/django/utils/connection.py#L72-L73
 doesn't create any connections] it simply iterates over
 `settings.DATABASES`.
