Hello boosters,

a design question: how often (if ever) and under which circumstances
do you use shared_container_iterator?

(http://www.boost.org/doc/libs/1_49_0/libs/utility/shared_container_iterator.html)

I don't feel too good about allocating a vector<> on the heap but I
guess it was made for some reason and motivated by actuall need. What
are good use cases for such iterator? Obviously returning a container
from function (as presented in example) is not one of them.

Cheers,
Simon
