[hibernate-dev] Search: change in BackendQueueProcessorFactory public interface.

[Sanne Grinovero]

Hi,
there's another urgent reason to change BackendQueueProcessorFactory:

To finish HSEARCH-268 I only need to shutdown the executors created
during initialize();
there is no stop() or shutdown() method; I am not having a way to
cleanup similar and opposite to initialize()

my patch is working well until application shutdown: JVM will stay
waiting forever;
more details on JIRA soon.
