One should be suspicious of any case where write_lock is performed

Hello,
As one of usual tests I run the following script:
for i in `find /proc -type f`; do
echo -n "cat $i > /dev/null ... ";
cat $i > /dev/null;
echo "done";
done
This time the culprit is /proc/net/packet. cat process gets killed
$ cat /proc/net/packet
Segment
