--- Comment #4 from Adrian Chadd <adrian@freebsd.org> ---
I'm still verifying it. I've added some printf()s to see what triggers and
where.

Is it possible that the initial check will succeed but something will sneak in
between that check and actually trying to add the lock? The actual sx lock
isn't held for the duration of all of that.

I admit I'm not familiar at all in this code.
