This is *not* guaranteed, by code or documentation.  It is quite
possible for relaynews to emit Xref: as other than the first header,
so writing code that relies upon Xref: being the first header is
unwise.  (Consider an article with an enormous header which triggers
Plan B of article filing: since the newsgroups aren't known for
certain when the first headers are written to disk, an Xref: cannot be
emitted before writing the start of the headers to disk.)

hurry up and speed up.
