5266	mapped_region::flush improvement	dmitry_b@…	Ion Gaztañaga	"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.
