This has been an occasional issue (almost exclusively by people using
emacs on Linux console...) since I added the control sequence to
xterm in 2003.  But actually (checking the history), the combination
which you're commenting on dates back at least another ten years for the
AT&T terminals.

As I recall it, the problem is that emacs mishandles the very-visible
cursor setting:

       cursor_visible                cvvis      vs        make cursor very
                                                          visible

and rather than treating it as something for occasional emphasis, emacs
just uses it routinely.  On exit of course, it resets the cursor to "normal".

Since the feature's listed in the terminal description so that applications
know _how_, it seems that the place to fix it is in the application (emacs).

So... isn't there an emacs setting to make it leave the cursor alone?
