I understood it as working sort of like for TCP, where packages from a
given remote host+port all end up at exactly one of the local sockets? If
the idea is to split the workload over multiple threads holding their own
sockets listening to the same interface+port, wouldn't sending all packets
to all sockets all the time be kind of counterproductive?
Of course, I haven't actually used it much; I might be wrong.
