Concerning 2.4+: RewriteLock was replaced by the more general "Mutex" 
directive. But indeed in seems in 2.2 you had to define a RewriteLock

Yes, I only made that change in the 2.2 docs. I suppose 2.0 needs it, too, but I've stopped doing anything with 2.0. I suppose we should probably not do that quite yet.
