Can serf recover a single cluster following a "long" network partition?

If there is a network partition for a long period of time can serf automatically recover? To define some terms:

* long - longer than suspicion timeouts (ie all nodes across the partition are confirmed dead)
* recover - combine the resulting two clusters into a single cluster

For example, there are four nodes `A`, `B`, `C`, and `D`. A network partition causes `A` and `B` to be isolated into their own cluster, and `C` and `D` are isolated into a separate cluster. Now the network is fixed. Will the two split clusters be able to recover and form a single cluster with all four nodes?

One could manually heal the split by adding a node with peers from both clusters.

Thanks for the awesome project!
