This routine will only be runnable by the DBO by default, I expect? [Update, I see you discussed this on DERBY-5578]

> We should document the procedure that will get added as part of DERBY-5578. The new procedure will invalidate all the stored prepared statements. When such an invalid stored prepared statement is executed next time, it will get recompiled at that point thus generating a new plan for it. This can be a very useful tool from support point of view, especially after upgrades.
