### Please describe the problem.

I quickly searched but could not find exactly the same issue, so filing it new, but feel welcome to refer/close if it is already filed.

Upon some transfers between local hosts, I am getting some files failing to be transferred upon initial run, and I need to rerun `get` to get them.  Could may be `annex get` internally retry a few times (I think the same is done for http already) upon transfer failure?
