bump. This problem is still an issue. notinredmond's thread established that the more background applications you have running, the more likely it is to freeze. FYI, just yesterday, on a clean reboot, the game crashed on my computer (triple-core AMD). There *were* background apps running, i think -- steam, skype. Also, I had found advice that set the affinity of the software to one processor, but it was crashing anyways.
This works perfectly!
