This would break existing programs that use TCP_MAX_PRIO, since these would
be killed in current lwIP versions but won't be in future versions with this
< instead of <=  change.  Maybe we want:

#define TCP_NO_KILL_PRIO (TCP_MAX_PRIO+1)

And recommend using TCP_NO_KILL_PRIO for pcbs that cannot be killed due to
inactivity.
