<p>We can also make the intialized a tri-state, so that value of 1 means initialized, and 2 means initialized + rotated, to get rid of <code>was_rotated</code>.</p>

<p dir="auto">I've removed the <code>initialized</code> variable instead, which was not being used.</p>
<p dir="auto">I've also removed the <code>x</code> variable. Thanks for pointing this out.</p>
<p dir="auto">Removing <code>session_ticket_key</code> and <code>previous_ticket_key</code> seems feasible, but will need a bit more work, and I don't have time now. I can write this down and address it later if you want.</p>
