Thanks for the explanation, it confirmed my understanding!

Dave enlightened me on the advantages of using boost::shared_ptr a
month or so back.  Unfortunately I am not in a position to change my
code at this time for two reasons: (a) I'll need to investigate if
there is a performance hit for my kind of code (b) I don't have the
time to change the interface in my code right now and carefully
eliminate cyclic reference loops etc.

Storing pointers in a vector is asking for trouble?  It might be true
in general but I'd say using pointers carefully is not bad.  It has
worked well for me so far.
