This seems to work quite well, can run individual test cases under
valgrind and (although slow) it shows any memory safety issues.
Replaces the valgrind false-positives fix previously applied in 8407159.
That one effectively disabled gc roots from being marked, so things would
be garbage collected even when there were valid references to them.
