The problem is that there's too little entropy on those names and as such to a human they look the same. In the current version of the patch, you have only one out of six characters different and that's in the middle of the word--very hard for a human to see, note and distinguish. The situation is even worse with "real_rptr" and "real_wptr", as that's one out of nine characters different and still very hard for a human to notice the difference. For this reason I suggested, using "writep" and "readp" which are immediately distinguishable from each other as they have high entropy. Now, what they mean, you can put that in a comment, but please use names with high entropy in them, i.e. they are different from each other and easily distinguishable by a human. Regards, -- Luben
