Summary:  this test, when run on Windows, fails intermittently because 
of asynchronous windows deletes.  The test passes, deletes two files 
that it has created for the test in the scratch directory, and exits.  
Then, jtreg upon attempting to cleanup after the test, tries to delete 
the files after doing a listFiles() on the scratch directory, which 
despite the delete by the test itself, still contains the files.  The 
jtreg delete fails and jtreg changes the state of the test from passed 
to failed.

I'm in the process of adding deletion retry behavior to jtreg, but in 
the meantime we think it makes sense to provide a more stable test 
environment by simply getting rid of the redundant deletes by the test 
itself.  There really is no need for tests to delete files from the 
scratch directory at the end of a test because jtreg carries a guarantee 
of cleanup.

Thanks,
    Jim
