Its overkill in that case. The concurrent additions and removals can't happen.
BTW, if we talk about overkills: is there any reason to do these for & while until the end? I can't see why anybody should add the same *bstats & *rate_est more than once (or max twice if we let to add, change & remove them independently). With a large number of classes this could matter.
