No. This is a result of a bredth-first algorithm interacting with a depth first algorithm. The way the ports are created is antithetical to the way rm -r walks the tree. Basically, the prots collection is created incorrectly, and needs to be ficed. This has been discussed before, ad nausium, with no one with commit privileges doing anything but damaging the performance of the generic FFS to try to (unsuccessfully) optimize this particular corner case.
