Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.
Full build log is available here:

https://people.debian.org/~sanvila/build-logs/202610/

After trying 21 times, this package failed to build for me:

100% of the time on machines with 1 CPU
 46% of the time on machines with 2 CPUs

Therefore I recommend GRUB_CMDLINE_LINUX="nr_cpus=1" to reproduce.
(And, if that does not work, I can offer a VM, as always).

Thanks.

Fixed sys.modules leak between dynamic worker tests

Fixed a sys.modules state leak between the in-process dynamic worker
discovery tests in stestr/tests/test_test_processor.py that leads to
