Glad it all worked out in the end.

In general, you should only have to worry if housekeeping takes  
longer than the connect period on the client. It only interrupts  
housekeeping if the connection is for the currently processed account.

I agree. Once we've got the new version released, I would like to  
design a new storage system which doesn't require scanning of the  
account. I'm thinking of a nice reference counted scheme.
