Comment 11 for bug 245716

The problem is not entirely that files are not created in /tmp, but rather that nothing cleans them up in the event of a crashed or killed process. I also see these files in the current directory as well as tmp and .cache

As these directories are prefixed with a dot, less technical users will probably not see them as the default in the file manager is to hide them. I found over 2.5GB of these files on my system, which means they are also taking up backup space and resources, too.
