+// --- FAIL: TestPEXReactorRunning (11.10s)
+// 				pex_reactor_test.go:411: expected all switches to be connected to at
+// 				least one peer (switches: 0 => {outbound: 1, inbound: 0}, 1 =>
+// 				{outbound: 0, inbound: 1}, 2 => {outbound: 0, inbound: 0}, )
+//
+// EXPLANATION: peers are getting rejected because in switch#addPeer we check
+// if any peer (who we already connected to) has the same IP. Even though local
+// peers have different IP addresses, they all have the same underlying remote
+// IP: 127.0.0.1.
