Ok, well, I think that it's going to be hard to parallelise GridFlow like 
that, because almost all loops are medium-sized (more than enough for 
SIMD, but far from making sense for multithreading) and/or it makes too 
many calls to other functions in other objects that will have to be 
waiting for data to come in, due to GridFlow's packet-oriented nature 
(packets more like TCP/IP, not like PDP, but still based on 
function-calls).
