Method documentation is insufficient for Shuwdown operations

[git-hub-user]

I am confused by the 4 methods related to shutting down:

- public void Shutdown()
- public Task ShutdownAsync()
- public void ServerShutdown()
- public Task ServerShutdownAsync()

Are the following observations correct?

1. After some fiddlig, I found out that Shutdown() shuts down the parent RServe process and the forked child processes. ServerShutdown() shuts down only the child process for the connection it is being called upon.
2. ServerShutdown() has a comment "This command is asynchronous!", but this is not actually run asynchronously.
