Remove
     Users should not depend on the memory sharing semantics of vfork() as
     other ways of speeding up the fork process may be developed in the
     future.

as we are not planning to deprecate vfork. Besides NetBSD's
compatibility policy means we wouldn't change it anyway but introduce
something new.

Add
     Portable applications should not depend on the memory sharing semantics
     of vfork() as implementations exist that implement vfork() as plain
     fork(2).

because this is or used to be a real hazard.
