Test bug 917259, where app-alternatives/gzip is upgraded before its pigz RDEPEND is installed. This is triggered when find_smallest_cycle selects a large cycle and the topological sort produces poor results when leaf_nodes returns app-alternatives/gzip as part of a large group of nodes. This problem might be solved by implementing a finer-grained ignore_priority for leaf_nodes calls.
