If you have many TCP connections to one target it may happen that you get the same source port on the originator again within the TIME_WAIT timeout. And if the ISN wrapped in the meantime the new connection will 'hang'.
Just to clear this up, the problem with randomized source ports and TIME_WAIT is not that the ISN is wrapping. The problem is that if a port is reused too quickly, the ISN has not incremented enough and is less than the final sequence number of the previous connection.
There's code in 5.3 which eliminates this problem by incrementing a global offset for each connection established, I will probably MFC it before 4.11 so that this problem is over with once and for all.
