CancellationTokenRegistration disposal.

should i dispose CancellationTokenRegistration for global shared CancellationTokenSource's token (eg: that token only exists while application is running)?

Scenario:

Simple console app that listen for TCP connections recv/send data.

Context:

Server.StartListen(token)

Server.StartListen(token)

token is global cancellation token source's token. For each new connection accepted, its forward token too for these methods (don't need to allocate own token source because it will not be used elsewhere).

Once accepted, new connection is created and server call

Connection.StartAsync(token)

Connection.StartAsync(token)

will forward too the token, its a blocking task that will complete both read/write tasks complete (or fail but exceptions proper logged).

But if server cancel token source early, the token registration will call
