Good suggestion.

I'll add a oneWay boolean attribute to AbstractPacket.
In the packet handler, before leaving the handle() method, I check if there is a response to send or if the oneWay boolean is set to false on the request.
If the boolean is set to false, I'll send a NullPacket() to "unblock" the client side.
