Maybe it could be the user process that resets the timeout so that it
never expires. If the user process fails to do this, then it is an
un-cared for zombie and so the kernel should kill it rather than fill
the conntrack hash full of zombies.
Naturally the user process can kill the contrack when the user process
thinks it should have expired.
