Don't populate cleaning policies during initialization procedure so the user
has to call the latter explicitly.
Until now cleaning policies could be populated in two ways:
- implicitly during cleaning policy initialization,
- explicitly be calling populate.
The difference was that the former was single threaded.
This patch removes the functionally redundant and less efficient code.
