Well, Martin compiles and _runs compiled tools during the office build.
So libkse can reboot the machine :)

BTW, I can reliably crash libkse programs on a SMP box using a trivial
code snippet. It looks like kernel is trying to lock an uninitialized or
freed mutes and dies with trap 12 while holding a sched_lock spinlock.
Not a pretty sight. The offending line is kern_mutex.c:598. Sorry, no
backtrace yet thanks to schedlock.

I will try to gather more details tonight.
