Cleanly applied against RELENG_9_0.

As my case was not exactly the same as Kris or Stefan I'd wait their 
feedback but as far I concern, *it works perfect!*.

[....]
%sysctl kern.version | head -n1
kern.version: FreeBSD 9.0-RC2 #1: Sat Nov 26 10:24:38 CET 2011

%uptime
12:06PM  up  1:30, 3 users, load averages: 0,07 0,08 0,10

%vmstat -z | head -n1 ; vmstat -z | grep reass
ITEM                   SIZE  LIMIT     USED     FREE      REQ FAIL SLEEP
tcpreass:                40,   1680,      58,    1370,  276624,   0,   0

%sysctl net.inet.tcp.reass
net.inet.tcp.reass.overflows: 5
net.inet.tcp.reass.cursegments: 17
net.inet.tcp.reass.maxsegments: 1680

%netstat -s -p tcp | grep mem
                 5 discarded due to memory problems

I'll leave the box stressing the tcp stack a couple of days, just in case.

Thanks a lot.

Raúl.
