> In discussion for other efforts, we decided that we should separate several
> concerns:
> * A posix-like FileSystem/FileHandle object (stream-based, positional reads)
> * An ephemeral ReadOperation object that holds the state for
> reads-in-progress, which consumes
> * An immutable FileInfo object which holds the block map and file size (and
> other metadata about the file that we assume will not change over the life of
> the file)
