Comment (by dgoulet):

 Replying to [comment:2 arma]:
 > B) I wonder if this is a side effect of the "if you need an intro point,
 launch two and use whichever finishes first" logic. If we even still use
 that.

 We do not. We only do that when the first intro point circuit reaches a
 "long enough time" that we'll relaunch one. See `circuit_get_best()`. The
 timeout value before we do such a thing can changed but basically is:

 {{{
   SET_CUTOFF(c_intro_cutoff, get_circuit_build_timeout_ms() * (14/6.0) +
 1000);
 }}}

 The only time we use parallel intro point is when we need a full set of
 IPs like a new descriptor or at startup. We launch 5 and pick the first 3.
