Nice.  I agree that your implementation is better.  I think this would make
a
nice addition to boost::smart_ptr, until we can agree on a policy-based
design, which is obviously getting a lot of different opinions right now
(which
is probably good).

Except that right now, counted_base is in the detail namespace. ;)  It's
easy
enough to pull it up, though.  I like the fact that counted_base is a usable
reference implementation for a reference-counted base.  I also like the fact
that if I don't want to use weak_ptrs with my classes, I can simply create
my own base class and not pay for the weak_count.  Now all I want is a
serial_ptr. ;)
