CI jobs (run on the Github Actions servers) seem to fail randomly, especially the "parallel tests" and "long tests".

#271 attempted to fix this, but does not seem to have been entirely successful. Since #271 was merged, up to 3/10/2024 we have not had any parallel test failures (apart from one macOS case that timed out, which is not the problem this issue is about), but several "long test" jobs failed. These latest failures are all in the "restart interpolation" test - the "restart full-f from full-f, 2V/3V", "restart full-f from split 1, 2V/3V", "restart full-f from split 2, 2V/3V", and "restart full-f from split 3, 2V/3V" cases.

The CI failures still are not quite gone after #274. The parallel macOS job seems to fail intermittently. It times out. I think it might be taking a very long time to do the 'Jacobian matrix' tests, but need to check this. If it is the Jacobian matrix tests, maybe they take too much memory? If so, I guess we could either skip (some of?) those tests in CI on macOS, or try to reduce the resolution a bit to reduce the memory usage.
