Lately, create-installer fails due to tcp-read: error reading:

• https://github.com/racket/racket/runs/803310055
• https://github.com/racket/racket/runs/792568732

Would retrying for a couple of times make sense here? https://github.com/mflatt/s3-sync/blob/master/main.rkt#L408

Is it failing every time, or just occasionally?

afaict just occasionally.

Could be a bug in so many different layers

Sigh
