T130207 is about a test in pywikibot/i18n falling because the CI job 'npm-node-4.3' creates a $WORKSPACE/log directory which pollute the sources.
We should get the repository(ies) checkout under a directory such as $WORKSPACE/src and run commands in there. Then if we want to generate build artifacts / log etc, people would reference ../log which is $WORKSPACE/log.
- Move all jobs to clone under /src/
- Document the workspace layout (/src/ and /log) somewhere
