Description

I'm not really sure if this is a problem.  I don't think GLOG should be enabled if using Python anyways.  However, I have it turned on for my local builds since I use it sometimes for instrumentation.  Recently, when running python tests I get the following failure from test_memory.py

 

    def check_env_var(name, expected, *, expect_warning=False):
        code = f"""if 1:

            assert pool.backend_name in {expected!r}, pool.backend_name
            """
        env = dict(os.environ)
        env['ARROW_DEFAULT_MEMORY_POOL'] = name
        res = subprocess.run([sys.executable, "-c", code], env=env,
                             universal_newlines=True, stderr=subprocess.PIPE)
        if res.returncode != 0:
            print(res.stderr, file=sys.stderr)
            res.check_returncode()  # fail
        errlines = res.stderr.splitlines()
        if expect_warning:
