chunked reading with -m plain #40

It would be nice to have a

read_sub : string (** filename *) ->
             ?start:int ->
             int (** length *) -> string

-like function to limit the amount of duplicate memory lying around

Is it necessary in the first place to split files in chunks with the plain module? If the chunks aren't directly accessible we're just re-concatenating the files everytime it's accessed. I guess the size limit is just the length of OCaml strings, right?

@MisterDA I believe so, yes - but OCaml strings are pretty small on 32bit machines. For 64bit it's probably not needed.
