	It's smort of an OS issue, but it is reported to
	applications, which have to be
	a) large-file safe -- it  causes  no  data
     	   loss  or corruption when it encounters a large file. A util-
 	   ity that is large file safe is unable to process properly  a
	   large file, but returns an appropriate error.
	b) large-file aware  -- if it can process large
	   files  in  the same manner as it does small files

	We're sorta large-file aware, but only on systems which
	support large files: on those we're large-file dozy (;-))

	We really should handle functions which fail and set errno

     EFBIG An attempt was made to write a file that  exceeds  the
           maximum file size or the process's file size limit, or
           the file is a regular file and an attempt was made  to
           write  at or beyond the offset maximum associated with
           the corresponding stream.

	Alas, we don't, which poses a problem on systems which
	are in transition between small- and large-file capable.
