Hudson test case leaks temp folders

      Description

      I have noticed that the HudsonTestCase sometimes does not do a proper clean up
      of the temp folders. On Windows this happens every time because of a file in use
      error. On Linux (debian) this sometimes happen if a test fails. As the temp
      folder can contain up to 14mbs, the total size can grow quickly.

      After 1 month of developing/testing my hudson test case folders consisted of
      500+k files in 892 folders, amounting to 7+Gb. (Windows)

      Maybe we can use the new TemporaryFolder rule that is available in JUnit 4.7, so
      we can lift out stuff from our implementation? http://github.com/KentBeck/junit/raw/23ffc6baf5768057e366e183e53f4dfa86fbb005/do
      c/ReleaseNotes4.7.txt

      Steps to reproduce on linux:
      1. Clean out all hudsonXXXX folders in the temp folder
      2. Go to hudson/plugins/seleniuma
      3. run "mvn test" and watch it fail
      4. Check the temp folder

      Expected result:
      No new folder in the temp folder

      Actual Result:
      A folder named hudsonXXXXXXX has been created

      Steps to reproduce:
      1. Go to hudson/plugins/ci-game
      2. run "mvn test"
      3. Watch output

      Expected result:
      Test fails

      Actual Result:
      An exception is thrown during the test clean up:

      java.io.IOException: Unable to delete
