@sipa Just an idea, why not always switch to a node that announces more blocks than the current syncnode, if we are up-to-date with the current syncnode?

Nodes can easily lie about the number of blocks, so this would be an easy way to introduce a DDoS attack. One could just pretend to have lots of blocks and everyone will switch to you and hold up the network.

Syncnode is going away anyway in headersfirst - we download from all peers that claim to have the block we're looking for (well, syncnode still exists, but it's just used to start the headers-sync process, which is really fast).
