I finally got it:

printf "\033[22;0t"
	This stores the current icon and window titles on a stack.
printf "\033[23;0t"
	This restores them from the stack.

It works fine with xterm, has no effect on rxvt-unicode (which I
am using), though.

That might well be a termcap problem. I've got to look into this.
