That may have other sideeffects, however.

In FreeBSD 5.x, the TIME_WAIT timeout is not configurable, but time_wait 
sockets are stored in a seperate hash table.  Also, they are now 
terminated prematurely when there is a shortage of ephemeral ports.  As a 
result, time_wait sockets are no longer the problem they were in certain 
situations under 4.x.
