Description
The memory mapped API in interprocess (http://www.boost.org/doc/libs/1_56_0/boost/interprocess/mapped_region.hpp) provides advise() while the memory mapped API in iostreams (http://www.boost.org/doc/libs/1_56_0/libs/iostreams/doc/classes/mapped_file.html) does not.
The iostreams API is easier to use (allows creating and sizing during construction), but is missing the key feature that would allow kernel optimization of random access versus serial.
