There are a few game engines that do this while running to detect bad hardware. The resulting 'bad hardware flag' is tracked and forwarded in crash reports to help sort them out from the 'real' crash reports (caused by bugs), and the information is also shown to the user when they hit an issue ('you seem to have bad RAM', etc). It'd be cool to see this turned into a reusable library that could be included by various types of software that is more likely to be impacted by bad hardware and can afford to burn a little cpu/gpu while it's running - you wouldn't want it in background services, but a game or high performance server app might be able to justify it.
