The bottom line is I would need a ~mutex() that discards errors and an 
atomic way of performing the following consecutive locks:

template <typename V>
     block_ptr & operator = (block_ptr<V> const & p)
     {
         mutex::scoped_lock scoped_lock1(ps_->redir()->mutex_);
         mutex::scoped_lock scoped_lock2(p.ps_->redir()->mutex_);

        ...
     }

But the latter would require locking a global mutex once again so 
there's no real gain of optimizing it because it already locks a global 
mutex.
