+- start two bitcoind nodes
+- create two transactions on node 0 - one is confirmed and one is unconfirmed.
+- restart node 0 and verify that both the confirmed and the unconfirmed
+ transactions are still available.
+- restart node 0 with zapwallettxes and persistmempool, and verify that both
+ the confirmed and the unconfirmed transactions are still available.
+- restart node 0 with just zapwallettxes and verify that the confirmed
+ transactions are still available, but that the unconfirmed transaction has
+ been zapped.
