I would think that the hot channel cools from outside in (by radiation.. 
convection isn't going to have appreciable effect in milliseconds). So, 
as long as the center of the channel doesn't cool below the 7000K or so, 
then when the next bang occurs, the charge will zoom to the end (heating 
it up on the way).

So here's the calculation that someone could do.. given a particular hot 
core diameter, what's the diameter vs time curve look like.
