I contacted Gregory P. Smith, the buildbot worker owner, to ask him to have a look.

> I think there was a bug in the past in regrtest or tempfile where the temporary files for tests were not deleted and lead to disk space filled up in several buildbots.

regrtest now has a --cleanup command to remove all build/test_python_xxx directories. But this command cannot be run by buildbot on a worker which allows multiple jobs in parallel, since the command removes temporary directory of parallel jobs...

I fixed many bugs in regrtest recently to reduce the risk of leaving temporary files on the disk.
