There was a problem hiding this comment.
When the test fails, we only see something like:
subprocess.CalledProcessError: Command '['/home/serhiy/py/cpython/python', '-c', 'if 1:\n import os\n os.setpriority(os.PRIO_PROCESS, os.getpid(), 0 + 1)\n print(os.getpriority(os.PRIO_PROCESS, os.getpid()))\n ']' returned non-zero exit status 1.
Which does not give any information about the cause of the failure. You can use assert_python_ok() which shows the stdout and the stderr of the failed process.

LGTM.
Pure test PRs usually do not need a NEWS entry, but this bug potentially had a large scope.

Fixes #115596
Runs the priority setting logic from
ProgramPriorityTests.test_set_get_priorityin a subprocess to prevent the priority change from taking permanent effect.
