Well, arguably putting the log files in the temp folder so that they get cleaned up would be an improvement - currently the log files are never cleared without user action, and most developers don't even know the log files are created. I suspect that the other reason to not use some mktemp equivalent is that they wanted the names to have some logical order to them, it just turns out that ascending file numbers is a bad way to do this.
