Description

## The Issue
We used to have a feature in the old downloader that would retry peers if a download was stuck. The most common case of this is a file that's not fully reflected, but started downloading on a client. Currently, the download gets stuck, and not resumed until after restart. Previously, we would wait 30 seconds, retry, then wait x, retry in a loop a few times.
