Sorry, I'm obviously missing something in your meaning - if the mutex
doesn't "exist" what good is it to me?  What do you mean 'created'?
initted? something else?  In Win32 I'm talking about calling
CreateMutex().

I could wait and call CreateMutex() during the first usage, but then
I'm back to needing a flag/exchange to protect that, and it starts to
seem no better than what I already have.
