"The real-time one will guarantee that the buy program runs within a fixed period (eg 100ms).
But the non-realtime one will *usually* win the race."

Just out of curiosity, why do say that the non-realtime
one will usually win?  Are you assuming real-time 
guarantees come at the _expense_ of latency?  Isn't it
usually the other way around?

Lower latency guarantees usually come at the cost of lower throughput.

However, you can scale up throughput by increasing the CPU power you have available (within
Amdahl's Law, etc); the same is not, necessarily, true for latency.
