The change looks good. 

I know this pre-existing, but to me it feels a bit strange to return false if the NUMA-functions are available. Wouldn't it make more sense to return true, which would disable NUMA. This is not something we should change in this patch, just wanted to hear others opinions now when I stumbled upon this.
