-//
-// If the deadline actor determines that the deadline has expired, the socket
-// is closed and any outstanding operations are consequently cancelled.
-//
-// Connection establishment involves trying each endpoint in turn until a

-// deadline actor closes the socket, the connect actor is woken up and moves to
-// the next endpoint.

-//----------------------------------------------------------------------

-//
-// This class manages socket timeouts by applying the concept of a deadline.
-// Some asynchronous operations are given deadlines by which they must complete.
-// Deadlines are enforced by two "actors" that persist for the lifetime of the
-// session object, one for input and one for output:
-//
-//  +----------------+                     +----------------+
-//  |                |                     |                |
-//  | check_deadline |<---+                | check_deadline |<---+
-//  |                |    | async_wait()   |                |    | async_wait()
-//  +----------------+    |  on input      +----------------+    |  on output
-//              |         |  deadline                  |         |  deadline
-//              +---------+                            +---------+
-//
-// If either deadline actor determines that the corresponding deadline has
-// expired, the socket is closed and any outstanding operations are cancelled.
-//
-// The input actor reads messages from the socket, where messages are delimited
-// by the newline character:
-//
-//  +------------+
-//  |            |
-//  | start_read |<---+
-//  |            |    |
-//  +------------+    |
-//          |         |
-//  async_- |    +-------------+
-//   read_- |    |             |
-//  until() +--->| handle_read |
-//               |             |
-//               +-------------+
-//
-// The deadline for receiving a complete message is 30 seconds. If a non-empty
-// message is received, it is delivered to all subscribers. If a heartbeat (a
-// message that consists of a single newline character) is received, a heartbeat
-// is enqueued for the client, provided there are no other messages waiting to
-// be sent.
-//
-// The output actor is responsible for sending messages to the client:
-//
-//  +--------------+
-//  |              |<---------------------+
-//  | await_output |                      |
-//  |              |<---+                 |
-//  +--------------+    |                 |
-//      |      |        | async_wait()    |
-//      |      +--------+                 |
-//      V                                 |
-//  +-------------+               +--------------+
-//  |             | async_write() |              |
-//  | start_write |-------------->| handle_write |
-//  |             |               |              |
-//  +-------------+               +--------------+
-//
-// The output actor first waits for an output message to be enqueued. It does
-// this by using a deadline_timer as an asynchronous condition variable. The
-// deadline_timer will be signalled whenever the output queue is non-empty.
-//
-// Once a message is available, it is sent to the client. The deadline for
-// sending a complete message is 30 seconds. After the message is successfully
-// sent, the output actor again waits for the output queue to become non-empty.
