> *Problem*
> If message is to be sent to remote node, we just send it (surprise :-)). But if message
is to be sent to local node, we have a strange "optimization" - we process it synchronously
in the same thread. 
> This is wrong as it easily leads to all kind of weird starvations and deadlocks.
> *Solution*
> Never ever process messages synchronously. For local node we should put message runnable
into appropriate thread pool and exit.
