I'm not sure that shared memory is a right approach. Shared memory is
usually used to share the part of memory between several different
processes, not the same process. Therefor shared memory are something
that is OS-wide and using it to share something inside single process
is a bit overkill, besides, it can possible to run into several
troubles, for example, you have to ensure there is not collisions
between different processes and shared memory ids.

Personally, I more like the idea of giving the user some way to
specify an allocator for Singleton library's managing facilities
(lifetime_priority?). Some kind of create_using_std_allocator_ex, but
not for single singleton, but for library manager.
