And as usual you are completely wrong with your insistence of the one-solution "plasma physics". (with pp in parenthesis because you don't do pp, you just do buzzwords).
Creating a plasmoid is A possibility from MRX, it is not THE result, as you can clearly see from all the papers on reconnection in e.g. the Earth's magnetotail.
Current sheets in space plasmas are created by magnetic fields, not the other way around.
Magnetic fields have a tension:
http://latex.codecogs.com/gif.latex? {\bf T}_m = \frac{({\bf B} \cdot \nabla) {\bf B}}{\mu_0},
and magnetic fields have an energy:
http://latex.codecogs.com/gif.latex?E_m = \frac{B^2}{2 \mu_0}
Through the magnetic tension, the magnetic energy is converted to particle energy (acceleration).
So-called exploding double layers only make sense at the location where Alfvén, sort-of, observed them, and that was at the power brakers at a electric power station. When the connection is cut, there is a discharge through the air (like lightning) and there one can have the creation of a double layer and there is an "explosive"-like ending to the discharge, when the gap gets too larged.
