Milestone:  To Be Determined  |   Component:  interprocess

------------------------------+---------------------------------------------
 The function flush shoud be changed or made polymorf in order to have an
 ability to set sync flags of msync directly

 like this

 function mapped_region::flush(std::size_t mapping_offset, std::size_t
 numbytes, int flags)

 The following flags are defined for msync():

 MS_ASYNC
     Perform asynchronous writes.
 MS_SYNC
     Perform synchronous writes.
 MS_INVALIDATE
     Invalidate mappings.

 this is critical for some applications that shoud be sure that data if
 fully transfered to the device.

 Thanks for help.
