KS2010: Performance regressions

I'm not sure I'm confusing anything. I wasn't thinking about multiple variables. A number of the tests in the test suite seem to test mainly the compiler optimisations, since they are cpu bound. Hence, pointless (not *wrong*, just not adding any information) for the job to which they are often put. Of course you can argue that this is the users' fault: Let's call it "user education", then, instead of "criticism".
