CHANGES says about vfork():

        new vfork(2) implementation that has old 3BSD semantics, i.e.
                address space is shared _and_ parent is blocked.  This
                results in a fairly noticeable performance improvement
                in some situations.  [thorpej 980103]

That's all it needs to say.

CHANGES isn't a list of every single change to the system.  It's a
summary of "significant changes."

If you want a list of every single change to the system, read the
source-changes mailing list.
