Comment (by neel):

 Sorry for the delay, but I decided to come back to the patch and start
 over from scratch.

 I have two questions:

 1. Is checking the capacity of {{{sampled_entry_guards}}} from the
 {{{guard_selection_t}}} object okay for this patch?
 2. If #1 is okay, which capacity size should {{{sampled_entry_guards}}} be
 to return 1? Right now, I am guessing 3 guards. Should it be more? Less?
