That was the thay it was done in earlier versions of lwIP but it was dropped 
because it wasn't a very good way of doing things when the memory for the 
connection state was preallocated. Since there now is a fixed amount of 
connections, there is no need to use a smaller structure for the TIME-WAIT 
connections - they use the same amount of memory anyway.

Of course, in your case things are different because you do heap allocation 
of the TCP PCBs. I have been thinking about introducing limits to the amount 
of connections (determined by a dynamic configuration mechanism). That 
probably would be helpful in this case.
