Another choice is of course just to turn off desktop-save-mode, then exit.

What should it do instead?

i) Not turn on desktop-save-mode if you answer no to the initial
question:

     "Warning: desktop file appears to be in use by PID 3616.
      Using it may cause conflicts.  Use it anyway? (y or n)"

ii) Or should this question offer a third alternative, eg "(q) -
disable desktop-save-mode for this session"?

iii) Or should the prompt

    Directory for desktop file: ~/"

somehow offer an option to turn off desktop-save-mode?

iv) Something else?

If you try it, you will find you get adequate warning about overwriting
the existing desktop.
