Hi Igniters! When some node detects critical error, e.g. OOME, deadlock, etc, it should invoke some user-defined callback and then attempt to close itself gracefully. In order to make this possible we need to enhance Ignite interface by adding something like Ignite.onEmergencyClose(SomeClosure).
First, I'd like to get your feedback on this potential change. Then we can refine SomeClosure structure. -- Best regards, Andrey Kuznetsov.
