Follow-up Comment #1:
A tcp_pcb is allocated by (inderectly) calling 'tcp_alloc()'. The first thing
this function will do if allocation fails is to kill a pcb in time-wait
state.
If that doesn't work, let's debug it instead of adding more config options.
Also, a pcb in time-wait should not have any segments, pbufs or callbacks
attached, so it should only consume one tcp_pcb from the pool.
