I see.  Then I'd create a shared executor and forward tasks in
MessageHandler there.  Otherwise, you could create your own
ExecutorFilter that processes events simultaneously.  If you are using
trunk (2.0.0-M1-SNAPSHOT), then you could simply use
UnorderedExecutorFilter, which is what exactly you are looking for.

The solution I suggested above will fix your problem.
