> Just like we will create native Dir impl (UnixDirectory) to pass the right OS level IO flags depending on the IOContext, we could in theory do something similar with MMapDir.
> The problem is MMap is apparently quite hairy... and to pass the flags the native code would need to invoke mmap (I think?), unlike UnixDir where the code "only" has to open the file handle.
