It does NOT break the firewire driver, I have no idea how you come to that conclusion. 4Kb stacks have a lot of advantages. The most important one being that 8Kb stacks lead to quite a bit of latency for desktop use, and also cause a lot of VM mess (which also leads to desktop latency because far more cache than needed gets evicted by the VM for 8Kb requests, resulting in that cache having to be read back and thus latency for desktop). It also uses less memory and allows for more threads to be used, something which java and appserver people seem to appreciate.
