As Jaime pointed out, the main purpose of the patch is not make more flexible how memcache listen on ports, but when using udp be able to use 32 consecutive ports with one thread per port listening to get huge improvements in performance, less system and contention.
For this you usually need all ports to be contiguous (less configuration in the application side), and adapt your application to choose one of those ports randomly (per request, per frontend server...).
