Comment(by nickm):

 {{{
 +  if ((guard->first_hops % (unsigned)pathbias_get_min_circs(options)) ==
 0) {
 +      entry_guards_changed();
 +  }
 }}}

 That's a kludge, and I think it might be a needless one.  We can just say
 entry_guards_changed(), and that will cause a state write to happen in 10
 minutes or an hour, depending.  Am I wrong?

 Using "0" for the "never disable circuits" value seems a little worrisome
 to me; it relies on us using < rather than <= for when we compare the
 actual failure rate to the threshold.   Should I worry?
