Well, strange things happen. I've had such a side effect on my runvdr 
extreme with a closed stdout, see here: (German)

In this case, printf on kanotix complained heavily on a closed stdout, 
and the only workaround was to replace >&- with the traditional >/dev/null.

For now I'll maintain it, currently the differences are only minor. 
Adding some #ifdef detection is a good idea, I'll add that for the next 
1.4 patch.
