    In the past I have found that other libraries (like Hadoop) eat interrupts, so it may
never be seen.  I am not sure, but I was wondering if it would it make sense to have an additional
atomic boolean that you set and and check?  I had to do this to reliably interrupt scans in
Accumulo. If there were an AtomicBoolean, could do something like `if(Thread.interrupted()
|| stopped.get())`.
