I can't reproduce the CI fails locally.

Here are the things I tried running in CI:

• tried only running the prerelease jobs, but didn't trigger (434f208)
• running all linux test jobs triggers the issue (28da3eb). Could be that issue is intermittent?
• 3.11 with numpy-dev (a97687e) or 1.26.4 does not trigger the problem (28da3eb).
• only 3.12 with np-dev seems to trigger it (dfb4326). cp312+np2.3.3 does not trigger the issue (6142d7b).
• Adding an extra join into the MapWrapper doesn't do anything (303fbd0)
• only running one method doesn't trigger issue (9a42535)
• weirdly, with the setup that should trigger the issue, if you turn on debug logging, the issue doesn't appear (504d938)
• issue doesn't appear with cp313. Perhaps the workaround is to just modify the CI config to avoid cp312.
