One of my test boxes (an 8-way x86_64 software-development thing from Intel
- I'm not sure what's inside it) no longer powers itself off when I run `halt
-pfn'.
During bisection I found two different problems. Sometimes the machine
wouldn't power off at all. Other times it would power off after a pause of
around twenty seconds.
Bisection indicates that this commit is what caused the 20-second pause.
It could be that some later commit caused the infinity-second pause.
