Really good work.

I gave your results some thought and was thinking that maybe you should 
check to see if you reached the default 1500 threading limit  of libthr 
and maybe it needs to be increased, I set mine to 40000 like below.

I was thinking it would be good to show threading usage activity with 
some kind of 1 second loop doing ps -auxwH | grep -c 'mysql' or 
something like that so we could see what limits its getting to, and so I 
can have an idea of what I can compare it to on my own servers.

Just a suggestion.
