      Context

      The TestCSOTProse test fails on windows [and only windows] builds in the CI:

      TestCSOTProse/8._server_selection/serverSelectionTimeoutMS_honored_for_server_selection_if_timeoutMS=0

      It's notable that unparallelizing just TestCSOTProse/8._server_selection/serverSelectionTimeoutMS_honored_for_server_selection_if_timeoutMS=0 resolves this issue.

      Definition of done

      This was introduced in GODRIVER-2348 to make CSOT feature gate behavior the default. It appears to be caused by parallelizing the subtests, which was added in GODRIVER-2653. On the surface, parallelizing seems reasonable since the URI uses "invalid" as the host, so the failpoint created in test #1 should not be realized. Determine why the CSOT updates suddenly cause this to fail.
