    It doesn't even have to be recursive if the COFU has been called before 
any thread is started.

    I can't follow Gianni Mariana's points at all. If the COFU has already 
been initialized, the COFU code reduces to:

acquire_mutex();
if(false) initialize_object();
release_mutex();

    That can't possibly deadlock with anything.
