Description DJ Houghton CLA 2011-03-01 17:38:30 EST 
When looking at the serialization code for LocalMetadataRepository, it appears that whenever we add a site reference, we mark the repo as dirty and re-write the repository. 

In a lot of cases, the references will be the same across multiple features and as the number of features grow, the problem becomes more apparent. This was noticed in a scenario in which the reconciler was being used to install roughly 2000 features. 

We should check to make sure that we really did add a new reference before writing out the repository.
