Perhaps the interprocess docs can be updated to show how to create a simple allocator from the heap for easy creation of these temporary copiers and how to cleanly provide the thunking between "normal" equivalent types (e.g. strings) and those used in memory regions (basic_string).
Interprocess allocators would require changes to support that and I need to think about it, but I definitely think it should ease this task, as it is demanded by users.
There's still no technical reason to require this copy, is there? Can't we come up with a solution that avoids this copy?
Without changing the container the copy (either implicit or explicit) is unavoidable. In those cases, maybe we can avoid a shared memory allocation (which will be always slower than a heap allocation) for that copy.
What's stopping us from changing the container? -- Olaf
