Errors in the following tests indicate the machine is out of space:

Failed to create directory [/home/helixbot/.net/AppWithSubDirs/1c1cf] for extracting bundled files. Error code: 28

I believe we do properly clean everything up, but perhaps we could do so more eagerly. For a number of test classes, we have a shared app where each test case bundles it differently. Only after all the test cases in that class have run do all those bundles get cleaned up (when the shared app is cleaned up).
