Igniters, Currently we have enum GridIoPolicy which defines thread pool that must process a message on remote node. There is a chance that extension developers will require to process messages in their specific pools. For now it is not possible.
How about changing GridIoPolicy to a set of byte constants so that plugins can register their own policies? This will not break backward compatibiliy as we alraedy write policy as byte, and will only require some starightforward refactoring. Vladimir.
