#valgrind To show the real benefits from resource-management objects one should run
valgrind --leak-check=full ./test/Test -r xml -d yes --order lex "Solution that leaks"
and
valgrind --leak-check=full ./test/Test -r xml -d yes --order lex "Solution that doesn't leak"
If you didn't git clone --recursive https://github.com/stefanofiorentino/mutex_lock, then you have to
git submodule update --init --recursive
