commit 706256afb6c844a0e6aaab2b60f4326b91aca2e9
Author: Florian Weimer <fweimer@redhat.com>
Date:   Mon May 8 14:32:58 2017 +0200

    support: Delete temporary files in LIFO order
    
    This is required to remove temporary directories which contain
    temporary files.  Previously, FIFO order meant that directory
    removal was attempted when the directory still contained files,
    which meant that temporary directory cleanup was essentially
    unsupported.
