[gnu.emacs] File mapping

eb@LUCID.COM (Eric Benson) (06/14/89)

Has anyone considered creating file buffers by mapping the file into
Emacs' address space with copy-on-write access on systems that support
it?  I believe PDP-10 Emacs did this on Tops-20.  I know SunOS 4.0 and
Mach support copy-on-write.
