Andi, you're being an idiot.

You are spewing endless and uninformed bullshit about this secure hash
topic, and it must stop now!

You obviously didn't even read my patch, because if you did you would
have seen that I don't initialize the random seed until MUCH MUCH
later _EXACTLY_ to deal with this issue.

In my patch the random seed is initialized when the first TCP or DCCP
socket is created, at which point we'll have sufficient entropy.

So please stop talking such nonsense about this topic.
