I'll agree to merge this change, but I still strongly recommend capping the retries, even with an exponential delay.  I'd really prefer to see 3 or 4 retries and then just gray out the EWF icon.  Then, allow the user to click-to-retry.  Anyway, that enhancement is already written up in the "EWF Enhancements" user story in Trello for this sprint, so I'll let that work add the changes that I'd like to see.
