I need to separate a clean source tree from a clean tracing runtime environment. I will rerun this in a fresh tracing environment and re-evaluate the testcase assumption before pushing anything further. If this testcase is only valid for a clean environment, then an unresolved check or a different precondition will make more sense than the current patch. Thanks, Cao Ruichuang
