/// The goal is to ensure that all worker processes are registered with the monitor for the active host.
/// There are a few different cases to consider:
/// - Starting up in normal mode, we register on when the process is started.
/// - When a placeholder mode host is specialized, a new host will be started but the previously initialized
/// worker process will remain running. We need to re-register with the new host.
/// - When the worker process dies and a new instance of this class is created.
