Thanks! (That's way cool stuff!)

My additions seemed to be done correctly EXCEPT for my omission of:

LINE 2: { &key_foo, "foo", ...},

(Oops!), which I realized after discovering that the
performance_schema table names are case sensitive on linux, and didn't
show any of the mutexes I had added ...

I also visited Marc Alff's blog and
http://dev.mysql.com/doc/performance-schema/en/index.html

Thanks for pointing me in the right direction!
