the container's job to deallocate its elems, and it's your job to destruct the

Lots of good learning points I appreciate the learning opportunity. So is what
you are explaining is that one would just pop the elements out of the vector and
then they would be deleted when this call is made by the resource that "owns" it
and is done with it:

Or are you explaining that when the pop is called, the internals of the vector
implementation invokes the destruction of the object.

Yes. And the allocation/deallocation is performed by the container, say, ComplexDataVector, when it needs to adjust its internal storage.

segment.destroy<...>(...) will destruct the found object and deallocate the memory.
It's analog of "delete".

I so appreciate your responses, it has been tremendously helpful. Working with
Boost Interprocess has made me think a lot more about the
allocation/deallocation process that tends to get abstracted away but is useful
in understanding.
