While rebuilding the python related packages against the Python 3.15rc2 version we found that python-loky fails to build from source [1]. Almost all the resource tracker tests fail, and this can be fixed by applying the upstream resource_tracker fix (5c28e6c) [2]. I've applied the upstream fix in the sandbox [3] to verify that it builds successfully, please consider applying the patch to support the upcoming 3.15 version. Setting the severity to important for now. Once Python 3.15 is released, it will be added to python3-defaults and this bug will become release critical.
