The completion variable interlocks the busy module with the concurrent loading of the target livepatch patches which works with the execution flow instead of estimated time delays. The test-klp-shadow-vars changes first refactors the code to be more of a readable example as well as continuing to verify the component code. The patch is broken in two to display the renaming and restructuring in part 1 and the addition and change of logic in part 2. The last change frees memory before bailing in case of errors.
