If that is the case what difference does your suggestion of not putting it
in test-lib.sh make?  We discourage users from playing ACL games, and we
protect ourselves from such by making sure the trash directory used for
running tests are not contaminated with ACL.  Wouldn't it make more sense
to do so for all the tests, so that future test writers do not have to
worry about it?
