Network.Mux.Bearer.AttenuatedChannel

An AttenuatedChannel supports:

• attenuation applied after reading a message from QueueChannel;

• two-way close handshake with 120s timeout. Read side is closed as soon as an internal MsgClose is received, write side has to be closed explicitly.

Attenuation of a channel.

QueueChannel is the low level bearer used by the simulated snocket.

Each read / write queues can be closed independently. Read queue is closed once MsgClose is read from the queue; dually, write queue is closed once MsgClose is written.

Make a AttenuatedChannel from a QueueChannel.

Create a pair of connected AttenuatedChannels.
