Saxon

When a query is evaluated using XQueryEvaluator.iterator(), there is no way of indicating that no further results are required (it returns a standard Java iterator, which does not have a close() method).

This is significant when streaming using saxon:stream(), because this involves a separate parser thread that is supplying data incrementally via a shared buffer. This thread remains in suspended animation waiting for the query thread to read data out of the shared buffer to make room for more data.
