This eliminates 1945 (432709 -> 430764) allocations from running `./tests/SelfTest -o /dev/null`. In general terms, this saves an allocation every time an unvisited `SECTION` is passed, which means that the saved allocations are quadratic in number of sibling (same level) `SECTION`s in a test case.
