Let it run for a few minutes, it was funny, then my Windows BSOD'd with an irql_less_than_equal error. I do have my memory timings changed/overclocked, but no other app or stress testing, including karhu, has caused an error in any way over two weeks of use until I opened and used this app.
So I think something is wrong with the memory usage. It wasn't leaking, it was only using 16mb, but still, that's kinda weird. Just a heads up.
