For 2.0.0rc1 pp39 windows wheel fails test collection

[charris]

See https://github.com/numpy/numpy/actions/runs/8485561340/job/23252932520. The relevant error seems to be

ERROR f2py/tests/test_abstract_interface.py - PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\RUNNER~1\\AppData\\Local\\Temp\\tmp5xhejvww\\meson.build'

NumPy v2.0.0b1 built and tested without problems and very little has changed. The only thing that might be suspicious is the upgrade of pypa/cibuildwheel, and the wheel built without problems, and I am not sure why that would affect meson using the file. The other candidate might be pytest-xdist, but it hasn't changed.

I am tempted to ignore this for the 2.0.0rc1 release, I don't think it is a blocker.

That last wheel build for main ran without problems 3 days ago. I suppose this could be affected by the same problem that has impacted emscripten.

Skipping it is fine. If we figure it out we can upload rhe wheel later

Took 4 tries, but eventually the pp39 wheel test did run. Looking back, the 2.0.0b1 release took 3 tries.

We have seen some problems with test collection caused by a garbage collection bug. Much of the problem has been fixed and will be part of the next release. See the issue and a blog post about it.

@mattip We should drop Python 3.9 for NumPy 2.1, is there any problem with PyPy on that platform?

[mattip]

PyPy 3.9 and 3.10 share as much as possible of the same code base, so new problems would be unexpected.
