duplicate simultaneous uploads
GWCelery hit a race condition in GraceDB's file versioning routine. Specifically, it occurred when a user uploads two files of the same name, so close in proximity to each other that creating a symlink fails because the link already exists. I can put in a retry to stop it from throwing up a 5** error, but it also got me looking at the superevent in question: S230504an.
So it uploaded preliminary-circular.txt
twice at the same time, and then again five minutes later. The five minute pause I get (completeness or something, and the file is different five minutes later). But the two files that were uploaded at the same time (log message 133/134, then 219/220) have the same content. Seems like it may be a bug
