Thanks for doing the unit tests. Yes, the hope is that this good is good 
enough for today's compilers, and that tomorrow's compilers will 
implement C23 memset_explicit anyway so this code will be irrelevant.

Given the underlying hardware issues, memset_explicit is best-effort 
anyway. (Plus, you should see how Emacs misuses it! Oh my. I suggested 
an improvement for that but there were objections and I haven't had the 
time or patience to wade through it.)
