* TODO:
+ * - track per-peer request latency (using new load API)
+ * - consider more precise latency estimation (per-peer & request) -- again load API?
* - implement test_load_too_high, make decision priority-based, implement forwarding, etc.
- * - consider more precise latency estimation (per-peer & request)
* - introduce random latency in processing
* - tell other peers to stop migration if our PUTs fail (or if
* we don't support migration per configuration?)
