Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:

Thanks for looking into it. I like to start with a separate test function which stays as close as possible to the problematic application. And you are right, this issue is also observable in test_OpenProcess but hidden by the missing broken.

v3: Removed separate test function and adjusted existing test.

looks good to me
