Comment (by teor):

 We should consider what happens when we blacklist guards for behaving
 badly.
 (Can someone check my logic here?)

 If a guard gets marked as Invalid, then it will be dropped from the
 consensus, and we'll stop using it as a guard.

 If a guard gets marked as BadExit, then we'll keep using it, which is what
 we want, because it's only interfering with exit traffic. (We hope.)

 Are there any other flags we use to mark bad guards?
