----------------------------------------
Nevermind. This is a different resource leak I'll file later if it hasn't been
fixed on trunk.
> Batch Scanner can get stuck when external thread closes scanner

> Scenario- client is using batch scanner to run queries with complex server
> side iterators. They run long. User has external thread which determines
> thread is running long, so that thread calls close on the batch scanner.
> Query threads exit nicely, but there is a thread which is constantly polling
> an internal queue. It only breaks out of that loop if there is a next key or
> an error thrown. If neither occur, it continues to poll. We should probably
> have an exit condition get set on close() which is used in that query loop.
