We used to have an interesting phenomenon in Windows 7 and SONAR called 'motor boating' and your description reminds me of that. It had to do with drivers and buffer adjustments, if I recall, and one of the CPU cores pegging at 100%. It required the Task Manager to shut down the program, just as you said. But, no one has complained about this in a few years. Mario and other SONAR users will remember this too.
