By the way, I just tried to understand that boost smart_ptr and weak_ptr
by looking at the boost code.  I personally find it basically unreadable,
but I have never been too good at templates.

If I make an attempt at re-doing the smart-ptr logic, I think I'll
use inheritance instead of templates, as I find that type of code
much easier to understand.  It's not as general purpose, since your ref-counted
objects must inherit from a common base class, but since I think ref-pointers
should be used sparingly anyway, that shouldn't be a problem.
