if you're using .NET 4, I'd strongly suggest using Parallel.ForEach (potentially on downloadList.Reverse())

so, something like:

Parallel.ForEach(downloadList.Reverse(), 
                 new ParallelOptions { MaxDegreeOfParallelism = 8 },
                 item => this.DownloadItem(item));

If you don't want the calling thread to block, you could QueueUserWorkItem this call, of course.
