In this test we connect to one node over p2p, send it numerous inv's, and |

compare the resulting number of getdata requests to a max allowed value. We |
|
test for exceeding 128 blocks in flight, which was the limit an 0.9 client will |
|
reach. [0.10 clients shouldn't request more than 16 from a single peer.] |
