_preconditionSafeToSyncShutdown(file:line:)
Must crash if it’s not safe to call syncShutdownGracefully in the current context.
func _preconditionSafeToSyncShutdown(file: StaticString, line: UInt) This method is a debug hook that can be used to override the behaviour of syncShutdownGracefully when called. By default it does nothing.

EventLoopto use, this is useful for load balancing.func shutdownGracefully(queue: DispatchQueue, @escaping (Error?) -> Void) Shuts down the eventloop gracefully. This function is clearly an outlier in that it uses a completion callback instead of an EventLoopFuture. The reason for that is that NIO’s EventLoopFutures will call back on an event loop. The virtue of this function is to shut the event loop down. To work around that we call back on a DispatchQueue instead.
