Crash on Socket.close()

[samlapse]

First, thank you for developing this fantastic lightweight server!

We've encountered a recurring crash, primarily when the iOS app is running in the background. The crash log is as follows:

Crashed: com.apple.root.user-initiated-qos.cooperative

To provide further context, here are relevant code snippets related to how we start and stop the server:

 func start() {
        Task {
            do {
                if await !server.isListening {
                    try await server.start()
                }
            } catch (_ as CancellationError) {
                print("Task cancelled")
            } catch {
                logger.error("Error local server: \(error.localizedDescription)")
            }
        }
    }

    func stop() {
        let task = Task {
            await server.stop()
        }
        task.cancel()
    }

Thanks!
