Yes, sorry, you are right, it should be deprecated and after that
removed, the same will happen, I'm afraid with
mapped_region::get_offset(). The problem with flush and shared memory is
that flushing into shared memory is unspecified according to POSIX::

"The effect of msync() on a shared memory object or a typed memory
object is unspecified"

Does flush() for shared memory useful in your platform?
