There is a short window between getting file info and deleting it, where it can be updated by other user and result in a missing S3 file. One option would be to move this code in transaction.

It seems that the current purge scripts are quite old. There are some incompatibilities. For example getLocalFileInfo($info) function wants 'zip' paprameter, but we don't have it, because all file names are just hashes. So it means we need a modified getLocalFileInfo function that doesn't use 'zip' parameter in query?
There was a 'TODO' mentioning to use SSCAN when it will be available in phpredis. Now phpredis supports getting multiple results with spop. What was the initial behind SSCAN? performance?
