There still seem to be test failures, e.g. on machine dci-macm1-build-009 running macOS-26.0.1 https://helixr1107v0xdeko0k025g8.blob.core.windows.net/dotnet-runtime-refs-heads-main-15b68bbf149843cbaf/System.Net.Sockets.Tests/3/console.ee98b396.log?helixlogtype=result

I think for now, it's better to disable all tests which is failing for this reason and open a generic tracking issue for this change in the infra.
