You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: portlist_windows.go
    path of file: ./repos/sliver/vendor/tailscale.com/portlist
    
    the code of the file until where you have to start completion: // Copyright (
    
func init() {
	newOSImpl = newWindowsImpl
	// The portlist poller used to fork on Windows, which is insanely expensive,
	// so historically we only did this every 5 seconds on Windows. Maybe we
	// could reduce it down to 1 seconds like Linux, but nobody's benchmarked as
	// of 2022-11-04.
	pollInterval = 5 * time.Second
}
