As mentioned already the proposed diff doesn't protect creation of cloning
devices via open(2). The above test could be replaced by:
for i in 1 2 3; do while true; \
do cat /dev/tun0& ifconfig tun0 destroy& done& done
The same could be applied to switch(4) or by replacing the cat(1) magic
with 'ifconfig bridge0 add vether0.
