I hit this failure in CI: https://github.com/PyO3/pyo3/actions/runs/5237094306/jobs/9455062113?pr=2709#step:19:732
I'm pretty sure what's going on there is that
pool_not_dirty()
is too strong an assertion - another thread which is testing putting a delayed clone or drop onto the pool can trigger a race. I was able to reproduce the same race before applying this patch.
