<http://boost.org/libs/smart_ptr/smart_ptr.htm> states that only
std::bad_alloc is thrown - if anything is thrown at all. Am I misreading
that?

And reading the documentation for weak_ptr, it's not clear to me when a
bad_weak_ptr exception is thrown at all. All weak_ptr functions are
documented to never throw.

BTW: In the introduction, it says that there are five smart pointer
classes, then it lists six... :)
