And you measured the time gain guaranteeing that it actually saves that
much time. Usually that isn't actually measurable ....

And the usual solution is to have a preprocessor symbol to allow people
with lots of time and/or "valgrind" and similar tools to clean up
cleanly and the speed gang can compile that code out.

Kind regards,
