Details:

Piero found this and posted on lwip-devel on 02.02.2009:

If TCP_LISTEN_BACKLOG is used, a connection that times out in state SYN_RCVD
(and is then purged) does not decrease the counter tpcb->accepts_pending. New
connections cannot be established.

Suggested solution: decrease listen_pcb->accepts_pending in tcp_slowtmr when
purging a pcb that is in state SYN_RCVD. Unfortunately, we don't have the
listen_pcb pointer here, so we will have to search for it in listen_pcbs.
