Code review comment for lp:~vishvananda/nova/log-fix

I will dive into this again in the morning, but what strikes me right away is that it feels unusual for logging to require adding an additional "initialized" attribute to Flags, my instinct is that this is a problem solvable by good practice rather than by force. If you'd like to explain further why it that needs to be done, that'd be swell and will make it easier to review again in the morning.
