Review Comment:
@potiuk @vincbeck @dpgaspar - I think we need to understand why we have to
do it here. If we don't the number of connections established to the database
grows infinitely when multiple apps are initialized in a single interpreter -
generally the connections **should be|** ref-count or garbage-collector
cleaned, but they are not.
