You might want to consider making an async getMetadata function; see
discussion ending at [1].  Async because the modification time can
change often, and as a generic all-metadata function because it's easy
to expand and experiment with.  And if you put that right in the File
API, then I can inherit it from the FileSystem API instead of having
to spec it myself ;'>.
