Help me find the pattern...

I once read a paper about a communication pattern. All I remember about
it now is that the messages to the object were placed on a stack to be
sent to the object (which could exist on another thread or another
computer.) If the message was to return something, the client would get
back a "Future" object, and asking for the value of the something inside
the Future object would cause the thread to block until the information
was available from the object on the other side of the boundary...

I thought the paper was connected to the ACE framework but I can't find
it now. If someone knows where it can be found, could you reply with a
link to it? TIA!
