Even if you somehow manage to prevent the system from swapping out the
memory used by Emacs to directly represent the buffer, other elisp code
that interacts with the buffer may end up copying portions of the buffer
contents to other locations in memory, or copied to other programs,
e.g. if a spell checking mode is used.
