Changes between Version 1 and Version 2 of Ticket #32611

v1	v2
1	1	Currently, `runtest.py`'s [https://github.com/django/django/blob/main/tests/runtests.py#L346 bisect_tests()] and [https://github.com/django/django/blob/main/tests/runtests.py#L397 paired_tests()] both call `runtest.py`'s `setup()` and `teardown()`. However, it doesn't seem like they need to (in full).

3		The `setup()` function's primary purpose is to temporarily set `settings` for the purposes of the test run, but `bisect_tests()` and `paired_tests()` both run tests in a subprocess, so settings modification doesn't seem like it should be necessary. The only things the call to `setup()` seem to be needed for in these two cases is to (1) do some initial logging of the test run, and (2) ~~to do some work to compute `test_labels` in the case that `test_labels` aren't provided. So those~~ could be factored out.
