It's relatively safe to do so. The only thing is that if it is
unmarshalled in the process where it was marshalled you will still and
up with a new array or hashtbl.
Exception are some complex datastructure which may require additional
care when marshalled. An example of which are the graphs of the
ocamlgraph library (even the functional one), but there is none in the
standard library.

This flag is never needed but there is cases where it is mandatory *not*
to use it (with cyclic data).
