(** [marshal_out_binary oh segment] is a low level, stateful, API returning
[oc, stop]. Once called no other API can be used on the same [oh] and only
[Stdlib.output_*] APIs should be used on [oc]. [stop ()] must be invoked in
order to signal that all data was written to [oc] (which should not be used
afterwards). Only after calling [stop] the other API can be used on [oh]. *)
