This cracks my shit up....SC2 Beta, complete with memory leaks:
Paged Pool Memory:
Players may experience a drop of performance or odd graphical issues after playing for long periods of time. Usually when this occurs a message will appear mentioning the players page pool memory. If you receive the overlay messages informing you of the problem you can try to lower your graphic settings and restarting your client/machine, or increasing the system's memory. Also ensure your drivers are up to date and all OS updates have been applied.
