What I get from reading these mails is that Per says that tcp_close() does 
*not* remove a CLOSED pcb from the bound list. If so, this would be a bug, but 
from reading the sources, it actually *does* remove it:

>>> snip <<<
    if (pcb->local_port != 0) {
      TCP_RMV(&tcp_bound_pcbs, pcb);
<<< snap <<<

Per, why does this not work for you? Can you debug it to sort this out?
