Hard-spinning again, inside gettimeofday() inside os_nsecs(). (The stack
above that point is corrupt, or at least gdb 6.7.1 won't show
it. Nonetheless if it's not stuck inside idle_sleep() I'll eat my
hat. Note that I am *not* running CONFIG_NO_HZ because, hah, I thought
that as rather new code it might be unstable...)
This *is* a change in behaviour: the backtrace is different! Yay! :)
