Comment (by nickm):

 To note: this class of bugs affects us not only when first starting Tor,
 but also when we're moving from one configuration to another: instead of
 causing crashes in that case, bugs like this cause us to look at facets
 configuration when we should be validating the new configuration, and
 therefore to report inaccurate information.
