The default shared_ptr constructor, which creates an empty shared_ptr, 
gives "use_count() == 0" as a post condition.  However, the documentation for 
use_count says it returns "an unspecified nonnegative value when *this is 
empty".  I'd like it to return 0 for an empty shared_ptr, as that appears to 
be the only way to distinguish an empty shared_ptr from one sharing ownership 
of a null pointer.
