Amend twice, unamend, then unhide.  This causes a cycle in the obsgraph.
  $ hg up -q 1cf4a5a0e8fc
  $ hg amend -m "feature1 renamed2"
  $ hg amend -m "feature1 renamed3"
  $ hg unamend
  $ hg unhide 74b668b6b779

Now cloud sync in the other client.  The cycle means we can't reliably pick a destination.
