Windows (or rather NTFS) doesn't allow deleting read-only files, which made us try to chmod +w first. But that is not necessery on Linux and Mac, and has led to unnecessary cache file mode changes, which was causing issues in shared cache scenario when a user that doesn't own a file was trying to automatically protect it. Fixes #3618
