Description
On my system, test_glob_named_pipe has been failing since it was added in #116421:
======================================================================
FAIL: test_glob_named_pipe (test.test_glob.GlobTests.test_glob_named_pipe)

AssertionError: Element counts were not equal:

I assume that it's because the self.dir_fd = os.open(self.tempdir) in setUp is done before mkfifo in the test, and the contents at open time show up in directory walk.
Indeed, if I change setUp to move some of the mktemps before the open, lots more tests start failing.
I'm on Fedora 39, kernel 6.7.9-200.fc39.x86_64, btrfs.
