So is this patch a "true" fix or just a temporary fix until further
work can be done on the problem?  I listened to Dan's initial
presentation and I've read a lot of speculation since then.  I've also
taken a look at the various blog entries that detail the problem.  I
believe I understand what the issue is and I can see how additional
randomization helps.  But it that truly an end-all fix, or is this
just the initial cry to stop short-term hijacking?
