/**
 * Protocol for sending information back from a worker process to the daemon.
 * 
 * This protocol is extended with the {@link WorkerLoggingProtocol} (for sending log messages)
 * and {@link WorkerProblemProtocol} (for sending {@link org.gradle.api.problems.Problem}s through).
 * 
 * Bundling these protocols together will use a single connection for all communication,
 * which means that messages are guaranteed to be delivered in-order (i.e. log and problem messages are delivered before the completion/failed message).
