-// Interface for receivers of messages from |ChannelEndpoint| (hence from |
-// |Channel|). |port| is simply the value passed to |ChannelEndpoint| on |
-// construction, and provides a lightweight way for an object to be the client |
-// of multiple |ChannelEndpoint|s. (|MessagePipe| implements this interface, in |
-// which case |port| is the port number for the |ProxyMessagePipeEndpoint| |
-// corresdponding to the |ChannelEndpoint|.) |
-// |
-// Implementations of this class should be thread-safe. |ChannelEndpointClient| |
-// *precedes* |ChannelEndpoint| in the lock order, so |ChannelEndpoint| should |
-// never call into this class with its lock held. (Instead, it should take a |
-// reference under its lock, release its lock, and make any needed call(s).) |
-// |
-// Note: As a consequence of this, all the client methods may be called even |
-// after |ChannelEndpoint::DetachFromClient()| has been called (so the |
-// |ChannelEndpoint| has apparently relinquished its pointer to the |
-// |ChannelEndpointClient|). |
