    DRILL-1942-hygiene (another preparatory patch):
        - add AutoCloseable to some classes
        - minor fixes
        - formatting
    
    Unit tests pass
    Regression suite passed except for some window function queries (this branch needs to
get rebased to pick up that code), and the known fragment distribution timeout.

> We're using a lot more memory than we think we should. We may be leaking it, or not releasing
it as soon as we could. 
> This is a call to come up with some improved tracking so that we can get statistics out
about exactly where we're using it, and whether or not we can release it earlier.
