Cassandane::Daemon kill_processes_on_ports() confused by same port/multiple protocol families #69

=====> Instance[1259] Can't send signal 15 to pid 12118: No such process

Observe here that it's trying to kill pid 12118 twice, even though the first time succeeded. This is because the process is listening to this port on both inet and inet6, and the algorithm looks up each protocol separately then concatenates the list of found processes.

Oh, we already have this open (by me, as well) as #59
