At the moment, it is very easy for an application to start a huge number of putAsync operations and fill the asyncTransportExecutor thread pool, delaying internal work such as state transfer. Increasing the size of the asyncTransportExecutor thread pool won't work, because that would in turn fill the remoteCommandsExecutor and JGroups' OOB thread pools, with the same effect. If the cache async operations used a different thread pool, it would be possible to configure a higher number of remoteCommandsExecutor threads than asyncOperationsExecutor threads, avoiding this problem.
