I used very heavy synchronization with one ObjectContext with child 
contexts. The exception was related to the shared URLs. I want to 
retrieve the row related to the URL if one already exists, other wise 
create a row and return that.

Using ObjectContext.localObject got me past the different ObjectContext 

Using Michael's warning about threads sharing contexts, and creating a 
synchonized block to handle adds got me the rest of the way.

So, now everything is working, and I'm not getting any errors or any 

Thanks Robert and Michael.
