> If a DME is sent during cleanup, that implies that the .close() of the
> LogicalIOProcessorRuntimeTask did not succeed and therefore these events are
> an error condition.
> These events should not be sent and more importantly should be received by
> the AM.
> Throw a clear exception, in case of this & allow the developers to locate the
> extraneous event from the backtrace.
