>From the "Auto-Save Files" node in emacs info:

    When you delete a substantial part of the text in
    a large buffer, auto save turns off temporarily in
    that buffer.  This is because if you deleted the
    text unintentionally, you might find the auto-save
    file more useful if it contains the deleted text.
    To reenable auto-saving after this happens, save
    the buffer with `C-x C-s', or use `C-u 1 M-x
    auto-save'.
