There was a bug in yanel that it didn't close the res-config repository 
upon shutdown.
I fixed this on 2008-05-13 16:36:47 (r36537).
Then I noticed that other repositories (ac-identities, ac-policies, 
custom repos) are not closed upon shutdown either. I'm not sure how to 
fix this. Maybe with a finalize() method of the 
IdentityManager/PolicyManager?

BTW, why is indexing enabled for the res-config repository of the 
yanel-website realm?
