Fwiw, I exposed this to the $#%# nest of reddit:
 
https://www.reddit.com/r/cpp/comments/are68n/experimental_readwrite_mutex/
 
Also, I edited my code to actually show the user what test they are
actually running!

The only change is an addition of some "helpful" code is in main:
________________________
int main()
{
ct_shared shared;
 
std::cout << "Testing: ";
 
#if defined (CT_TEST_FAST_MUTEX)
std::cout << "Chris M. Thomasson's Experimental Read/Write Mutex\n\n";
#else
std::cout << "std::shared_mutex\n\n";
