One question regarding this:

I have pretty persistent db-objects (I usually call reopen on  
exceptions), what happens if another
process changes these synonyms? are they stored in the DB, or just in  
the object-instance? Is a reopen on each search the best approach to  
reread synonyms if the are persisted on disk?
