Description
There are a number of regression tests which are not properly cleaning up after themselves on exit.

Some of the regression tests are using File.createTempFile() without cleaning up the dead files.  As a result, I had almost *36 GB* of dead space on sheen.  Obviously, that's a problem.  Builds were crawling or dying, spurious failures...etc...

The easiest way to avoid this is to use the following pattern:

    File f = File.createTemptFile(...);
    f.deleteOnExit();

rather than trying to catch your errors in case of failure.  In some cases, there was no attempt at cleanup at all, success or failure.

Please clean these up ASAP.  The changes are very easy.
