input/output_value are using Marshal under the hood, so it's going to be 
the same.

However, be aware that marshall (and the _value functions) are quite 
unsafe. If you have an error in the data (or your change the 
representation in OCaml), you will have ... surprising errors (including 
segfaults).

There are plenty of safer solutions for serialization (deriving, sexp, 
yojson, to name a few).
