Comment (by dgoulet):

 Plan B activated. Here is the development branch: `ticket15516_042_02`.

 So far working on the testing side. Requires unit tests and most likely
 better values for the rate/burst of the INTRO2.

 I still want to explore the idea of putting these knobs in the
 `ESTABLISH_INTRO` cell so an operator can tweak them at the intro point.
