if A, B and C are on different nodes one can assume very different 
transmission delays in such a manner that c-second will indeed arrive 
before a-second.

if they are on the same node i can imagine that the message passing is 
preemtible in such a way that a-second will not be delivered untila 
after c-second. not that such a message passing system would be a good 
idea, but it is possible.
