Policy based designs aren't bad. It's just that when I look at
boost::shared_ptr I see std::shared_ptr. The existing practice is that
things in the standard library are as thread safe as an int "by default".
Nobody complains that std::string should have a threading model parameter
since it can be (much) more efficient if it's only accessed from a single
thread.
