-// This test tests TLS session resume, by making multiple client connections
-// on the same port to the same server, with a delay of 200 ms between them.
-// The unmodified secure_server_test creates all sessions simultaneously,
-// which means that no handshake completes and caches its keys in the session
-// cache in time for other connections to use it.
-//
-// Session resume is currently disabled - see issue
-// https://code.google.com/p/dart/issues/detail?id=7230
