I tried (as my most ergonomic way to build something in a single-CPU VM): RELEASE=sid autopkgtest-build-incus --vm images:debian/trixie sbuild -Ad unstable --chroot-mode=autopkgtest --autopkgtest-virt-server=incus --autopkgtest-virt-server-opts='--vm autopkgtest/debian/sid/amd64/vm -- -c limits.cpu=1' pytest-httpbin sbuild -Ad unstable --chroot-mode=autopkgtest --autopkgtest-virt-server=incus --autopkgtest-virt-server-opts='--vm autopkgtest/debian/sid/amd64/vm -- -c limits.cpu=1' vcr.py Both passed - and I checked that /proc/cpuinfo indeed only reported a single CPU. So perhaps there's some other factor involved here, in addition to the number of CPUs. Can you see whether python3-urllib3 2.2.3-2 in experimental (just uploaded) behaves any better on your test system? That would be a sensible thing to try before any more arduous debugging, I think.
