Yeah, the fact that multiple threads are not just reading but might be
_writing_ the value really does make an `AtomicBoolean` make sense here. On the
other hand, there are no compound atomic operations against the variable, just
simple sets and gets. I dunno.
> allow ORDER BY sort to be cancelled

> Key: JENA-1212
> URL: https://issues.apache.org/jira/browse/JENA-1212
> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ
> Reporter: christopher james dollin
> Priority: Minor
> Fix For: Jena 3.1.1
>
>
> When a query with an ORDER BY is cancelled, the component
> Arrays.sort() that sorts the chunk(s) of the result
> bindings runs to completion before the cancel finishes.
> [See QueryIterSort and SortedDataBag.]
> For a large result set, this results in a long wait
> before the cancelled request finally finishes. This
> can be inconvenient.
