Scope clarification

This is not a Python 3.15 or shared-libpython failure. The failure came from TheRock #8394 CI, where the ROCgdb GPU job used Python 3.12.16 and the ROCgdb-specific no_rocm_image_ubuntu24_04_rocgdb test container.

The manylinux/Python 3.15 image is a separate, completed dependency: TheRock #9633 published digest sha256:f1f9dd9b..., verified with regular CPython 3.15.2 and shared CPython 3.15.0. #9688 does not modify that image or its shared libpython build.

Observed failure

The gfx94X ROCgdb test job ran:

python ./build/tests/rocgdb/test_rocgdb.py --parallel -f 0.25 --toolchain llvm --tests gdb.rocm

It produced widespread GPU-debug failures, including multi-inferior stress at 8/32 inferiors, stepping/fork/attach tests, and a 30-minute timeout. Cleanup found 33 lingering ROCgdb/GPU test processes.

Proposed change

At the ROCgdb revision pinned by TheRock (003062db3), --parallel sets FORCE_PARALLEL=1, selecting Make's check-parallel target. This PR tests serializing that GPU suite and extending its job timeout; it is a runner/test-stability fix, not Python enablement.

Lumachad correctly requested clarification because the behavior should be reconciled with the current test-runner implementation before merging. This PR remains draft while that review is resolved.

I don't think this is correct. The only thing the parallel invocation does at the moment is parallel compilation, which means we speed things up by pre-compiling everything. Tests are still run serially, one by one. Could you please clarify what problem you ran into?

This looks incorrect. Let's discuss.
