MWE to reproduce the issue with the least-squares optimizer. This will get stuck without using `.block_until_ready()` in the initial Jacobian evaluation. ``` import numpy as np from desc.examples import get...

On a related note, I'm skeptical that we don't need to use the coil current constraints for finite-beta equilibria. Using the final W7-X solution in the `coil_stage_two_optimization.ipynb` tutorial for example:...

I may have found an additional wrinkle to this problem, or else I'm not understanding something. As the simplest possible example, say we have a `CoilSet` with 2 coils of...

OK that probably explains it. But I still don't think this can be completely solved by scaling the variables. Because in my example above, the original ordering of the state...
