Matthias, was setting pba_sub = 255 causing material problems for
someone, or are you concerned that lossage will eventually occur on
certain server-class machines?

I ask because, while setting pba_sub that way is far from ideal, it
has worked well for me on a variety of machines, and if it has caused
anybody any trouble, I don't remember them bringing it up with me.
