no, can't be.
server and client are completely synchronous, in the sense that there 
are no pending requests at all.
new connection is opened only after previos has been closed.
besides, i set backlog = 511 when calling listen().
kern.ipc.somaxconn is 128, but you see that errors start to appear even 
before that number of requests.
