> The port layer currently has the following memory mapping API's
> hymmap_map_file()
> hymmap_munmap_file()
> hymmap_capabilities()
> However, these assume that a file exists, that it will be mapped read-only and that the
mapping will only happen to whole file.  All these assumptions are broken by the nio requirements,
so that the current NIO's mmap features are implemented by platform-dependent native codes.
