1381 * until they get a peer.

1389 * Okay, so here's how this *should* work now.
1391 * 1. We check the min heap for any peers that have 0 connections.
1392 * a. If any are found, we iterate over the heap and just randomly
1393 * choose another peer and ask testing to please connect the two.
1394 * This takes care of the case that a peer just randomly joins the
1395 * network. However, if there are strict topology restrictions
1396 * (imagine a ring) choosing randomly most likely won't help.
1397 * We make sure the connection attempt doesn't take longer than
1398 * the total timeout, but don't care too much about the result.
1399 * b. After that, we still schedule the find peer requests (concurrently
1400 * with the connect attempts most likely). This handles the case
1401 * that the DHT iterates over peerinfo and just needs to try to send
1402 * a message to get connected. This should handle the case that the
1403 * topology is very strict.
1405 * 2. If all peers have > 0 connections, we still send find peer requests
1406 * as long as possible (until timeout is reached) to help out those
1407 * peers that were newly churned and need more connections. This is because
1408 * once all new peers have established a single connection, they won't be
1411 * 3. Once we reach the timeout, we can do no more. We must schedule the
1412 * next iteration of get requests regardless of connections that peers
1413 * may or may not have.
1415 * Caveat: it would be nice to get peers to take data offline with them and
1416 * come back with it (or not) based on the testing framework. The
1417 * same goes for remembering previous connections, but putting either
1418 * into the general testing churn options seems like overkill because
1419 * these are very specialized cases.
