    Wait until any of the queries on the associated SQLContext has terminated since the creation of the context, or since resetTerminated() was called.

    Wait until any of the queries on the associated SQLContext has terminated since the creation of the context, or since resetTerminated() was called. Returns whether any query has terminated or not (multiple may have terminated). If any query has terminated with an exception, then the exception will be thrown.

    If a query has terminated, then subsequent calls to awaitAnyTermination() will either return true immediately (if the query was terminated by query.stop()), or throw the exception immediately (if the query was terminated with exception). Use resetTerminated() to clear past terminations and wait for new terminations.

    In the case where multiple queries have terminated since resetTermination() was called, if any query has terminated with exception, then awaitAnyTermination() will throw any of the exception. For correctly documenting exceptions across multiple queries, users need to stop all of them after any of them terminates with exception, and then check the query.exception() for each query.
