One of us has probably misunderstood the listen parameter.
It only limits the number of clients that can connect concurrently.
It has nothing to do with the number of clients that are already connected.
It sort of resembles a maximum queue size for the accept loop.
Incoming connections fill the queue, accept frees the queue by taking the
connection to a newly forked backend.
