Let handles be seen outside of `memfiles` module so that "updating"
operations (like eg., resizing a file and re-mapping) do not need to worry about race conditions of re-opened paths, renamed parent directories and that sort of thing. Operating directly on already open handles is both safer and more efficient than relying upon the stability of filesystem paths.
