------------------------------------------
The patch looks good to me. +1 I'll check it in.

> If the NM encounters an error while downloading a public resource, it fails
> to empty the list of request events corresponding to the resource request in
> {{attempts}}. If the same public resource is subsequently requested on that
> node, {{PublicLocalizer.addResource}} will skip the download since it will
> mistakenly believe a download of that resource is already in progress. At
> that point any container that requests the public resource will just hang in
> the {{LOCALIZING}} state.
