tsc test: Make the test more robust I've recently saw a lot of failures on running checktest test on virtual machines. Investigating further, it seems that running it into VMs just makes a conceptual problem more likely to happen: Since we're in userspace, the other thread that should read tsc can be out of the of the cpu at the moment, so all measures will be very different. This is indicated by the tsc roundtrip. In failed measures, they are all quite big. So I am proposing this patch, that basically ignores roundtrips that are twice as big as the threshold, or more. It makes the test pass to me, in machines I would expect them to. Also, remove the -static constraint on tsc's Makefile, since it will cause the compilation to fail in certain boxes.
