(** Simple forking parallel primitives. *)

val iter : ('a -> unit) -> 'a list -> unit
(** [iter f xs] iterates over each member [x] of the list [xs],
    running [f x] in parallel in a forked subprocess.  If [f] throws
    an exception then the function exits with an error. *)

val map : ('a -> 'b) -> 'a list -> bytes list
(** [map f xs] maps over each member [x] of the list [xs], running
    [f x] in parallel in a forked subprocess.

    The list of {b marsalled} values from [f] is returned - you have
    to unmarshall them (to get back the ['b]) using
    {!Marshal.from_bytes}.

    If [f] throws an exception, then the function exits with an
    error. *)
