I rechecked everything an noticed, that it wasn't a xterm, but a wrapper
script, that executed rxvt. I changed that to plain xterm and the zombies
were gone. So I think there was probably a bug in rxvt triggered there.
After that I redid the tests, with the same result (and no zombies).
I can feel no difference between 1+2 or 1+2+3.
