Comment (by teor):

 Replying to [comment:4 nickm]:
 > This looks safe enough on the high end.  But on the low end -- when
 n_intro_points_wanted is just 3 (the default) -- it takes the number of
 attempts per period from 10 down to 8.  Is that what we want?  (Non-
 rhetorical question. Maybe it is.)

 The limit was originally 2*(default + extra) == 10.

 But I think we want 2*default + extra == 8, because:
 {{{
   /* Allow all but one of the initial connections to fail and be
    * retried. (If all fail, we *want* to wait, because something is
 broken.) */
 }}}

 But I don't really mind either way, if you think it's less risky to
 maintain it at 10 in 0.3.0.5-rc, it doesn't make that much difference.
