looks like on 3.18.x and not master, passopenfile_test fails as it did in travis on macos?

and the failure:

    test_listen_outlive
test_listen_outlive: Starting test
   error: Received wrong-sized lament (0 != 27):

master is fine, locally I get a different failure

I re-disabled passopenfile_test, I guess it doesn't work well, sometimes? We'll see how it goes in master.
