+- start three bitcoind nodes
+- create four transactions on node 0 - two are confirmed and two are
+  unconfirmed.
+- restart node 1 and verify that both the confirmed and the unconfirmed
+  transactions are still available.
+- restart node 0 and verify that the confirmed transactions are still
+  available, but that the unconfirmed transaction has been zapped.
