 Replying to [comment:2 nickm]:
 > Please review branch "neuter_pathbias" in my public repository.

 The changes/ file is wrong -- the problem isn't that pb_disablepct could
 keep clients from building circuits at all (although it would have that
 effect on clients which use bridges); the problem is that pb_disablepct is
 a user-tracing backdoor which can be used to cause clients to cycle
 through all the available Guard nodes as entry nodes.

 Other than that, looks good for 0.2.3.x (I grepped for
 “`path_bias_disabled`” on that branch and didn't find anything else that
 turns it on).  There will be a merge conflict on 0.2.4.x.
