Comment(by lindi):
Well, my window manager (icewm) supports /proc/apm and I got very upset
when I suddenly noticed that it got stuck when I started the blinking
program :-)
Anyways, I tried reading other files in /proc and noticed that also
reading from /proc/driver/rtc seems to block forever. This probably
suggests that the problem is not APM related?
