Code review comment for lp:~etherpulse/podbird/duplicated_downloads

Time to review this. So I get most of the logic here. Before Podbird downloads an episode, it checks if the guid is already present in DownloadManager's list. What I don't get is why that delay timer is required. Can you explain that? Is it because DownloadManager takes a few ms to load and so this check needs to be delayed until that happens?
