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::

http://pubs.opengroup.org/onlinepubs/009695399/functions/msync.html

"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?

Best,
