We created a tmpfs directory on the two production slaves at /var/lib/jenkins-slave/tmpfs/ That directory holds the MediaWiki sqlite database and MediaWiki $wgTmpDirectory. We could use a cronjob to garbage collect the directories and files there.
The shell script creating the database garbage collect files that are more than one hour old. That collect them well though it is not perfect.
