Need some advice and comments (ponPonLoader: 4chan thread medias watcher)

<p>Should service&#39;s <a href="https://github.com/reinerRubin/PonPonLoader/blob/master/download_task_processor.go#L63">&#34;run method&#34;</a> be async or sync? Where I can read about standard approaches or check good sources.</p> <p>I have tried to implement a <a href="https://github.com/reinerRubin/PonPonLoader/blob/master/download_task_processor.go#L28">worker pool</a> which gives &#34;N&#34; chances to failed tasks. Is my attempt correct? Is there way to avoid buffered channels?</p> <p>I am also not sure about package grouping and <a href="https://github.com/reinerRubin/PonPonLoader/blob/master/thread_watcher.go#L37">&#34;thread watcher&#34;</a>. It looks quite messy.</p> <p>// <a href="https://github.com/reinerRubin/PonPonLoader">Github</a></p>
