    gvfs-test: More robust cleanup of temporary home directory
    
    Especially the trash:// tests have a tendency to leave the gvfs-metadata child
    around a little while after killing the D-BUS daemon, and thus leaving the
    temporary home directory busy. Retry for a few times to allow gvfsd-metadata to
    clean up itself.
