Re: Boost weak_ptr<>

AFAIK, it is for circle-of-reference problems.  If two objects have a 
shared_ptr to each other, they won't get deleted.  If one has a weak_ptr 
to the other, then hopefully things should work out, but you probably 
have to be careful (Haven't actually used a weak_ptr yet, but may need to).

Cheers
