Provide API to cancel a query like Hibernates cancelQuery

Hibernates Session interface provides a cancelQuery() method. Would it be possible to add this to EclipseLink? We have a application in which queries can be canceled by the user and currently we cancle everything about the DB query but have to wait until the DB query returns or fails with our predefined timeout.

Review the EclipseLink Session interface and Hibernate's cancelQuery() method as the stated reference point. Determine the API and cancellation behavior needed so a user can stop an executing database query without waiting for the predefined timeout; done means the capability is exposed and its behavior is defined.
