The two machines I've been able to reproduce this on have a root
partition of around 20GB. One has about 13GB of free space, and the
other has about 15GB of free space. hang.py is writing to /tmp so in
this case the writing and deleting is happening on the root file system.

hang.py is creating a bunch of files in /tmp/test and then deleting
them all from test/. So it's only deleting files, not a hierarchy of
any sort.
