Why?  What does ssh do that is gentler?

I suspect it then also depends on the `kill` signal.

In my WM (ctwm), I can also distinguish between `f.delete` and
`f.destroy` where the first sends something like a WM_DELETE request to
the application (which Emacs treats via `handle-delete-frame`, IIRC)
whereas `f.destroy` asks the X server to cut the connection AFAIK.

Would `f.destroy` be more like the `C-c` or the `kill` case of ssh?
