I have demonstrated it. See the other replies to Marcin. An that is only ONE
class of problems that can get worse with mutexes.

Also, the option of creating a mutex for each signle static initializer is
not viable, as mutexes are often precious resources you want to be in
control of. 

Or, if you don't, I want, so i restate my initial statement: do you want
this thing? then have it optional.

Bests,
