Galois uses GHC's rts for things that have to have low latency. Useful
* setting the heap size high
* using the threaded runtime system
* messing with the scheduler tick rate
* patching the rts to avoid slow bits (like deadlock detection)
I think since games and simulations aren't strictly "real time" you
should be ok.
