I'll definitely have a look at that, thanks Erwin.
But if the constraints are independent, then they don't really belong to the same optimisation problem, surely? Interdependent constraints can be solved simultaneously in a Jacobi scheme because the state of the variables are buffered from the previous iteration. Sorry if I'm completely missing the point before looking at the presentation

This was something I thought about, but didn't get around to trying out, sadly. The sychronisation points seemed tricky and slightly undid the effect of random constraint re-ordering.One could extend the common iterative methods to solve several sections of a single island simultaneously, making sure not to have two constraints working on the same body at the same time (note: that can be difficult to do efficiently). I don't think anybody in their right mind would suggest breaking up the system constraint-by-constraint, though.
