Suggested by Daniel (this should probably be more than one ticket):

• Streamline query intermediate format (incl. Serge's suggestions)
• Revisit QueryContext (split into QueryContext[incoming usercontext, read-only: username, db, auth] and QueryClipboard[derived namespacing, info passed between plugins)
• Think about nested namespace handling for subqueries
• Revisit analysis framework in light of current functionality and future optimization opportunity (if chunk totally contained in user area spec, eliminate area spec from chunkquery for that chunk).
• Is there a better way to materialize an analyzed query into many chunk queries?
