   7 - start three bitcoind nodes
   8 - create four transactions on node 0 - two are confirmed and two are
   9   unconfirmed.
  10 - restart node 1 and verify that both the confirmed and the unconfirmed
  11   transactions are still available.
  12 - restart node 0 and verify that the confirmed transactions are still
  13   available, but that the unconfirmed transaction has been zapped.
