Hi there,

When putting containers in shared memory, offset_ptr is used internally,
and IIUC, the iterator of the container will also use offset_ptr. But it
seems to me that in most cases we only use iterator locally rather than
putting those iterators in shared memory as well, so the
plain-old-raw-pointer is sufficient and hopefully more efficient for
iterator's usage.

What do you think?
