> In the thread [Giving a chance to buggy coprocessors to clean
> up|http://osdir.com/ml/general/2013-12/msg17334.html] I brought up the issue
> that coprocessors currently don't have a chance to release their own
> resources (be they internal resources within the JVM, or external resources
> elsewhere) when they get forcefully removed due to an uncaught exception
> escaping.
> It would be nice to fix that, either by adding an API called by the
> {{CoprocessorHost}} when killing a faulty coprocessor, or by guaranteeing
> that the coprocessor's {{stop()}} method will be invoked then.
> This feature request is actually pretty important due to bug HBASE-9046,
> which means that it's not possible to properly clean up a coprocessor without
> restarting the RegionServer (!!).
