Not new, but three very handy strings to commit to memory , especially for those of us that are pushing the limits of our dual 512's. I'm severe latency too regularly. Kernel will try to kill any process if it seems to have too many writes, also requesting all children killed as well. But if I hit a an unresponsive script or quick io rw's...its can take 20+ mins for the screen to unfreeze, if it can.
Now, I just need a Terminal open to input these...its looking like a reboot now...lol
