   reviewing this; too many other things have got in my way.
   
   I agree, with create overwrite=false, we must fail with a concurrency error
   
   what we don't want to do is overreact if we are doing overwrite=true and 
something does happen partway.
   
   I'll look at this in more detail, maybe focus purely on being meaningful on 
errors, in particular making sure that if the file is deleted before the error 
is raised, keep raising that concurrency error.

   fyi @saxenapranav @mehakmeet
   
as well as improving diagnostics, this patch also changes the recovery code 
by handling a deletion of the target file between the first failure and the 
retry.
