  Create a db_home directory with a unique name so multiple users can
  run the test simultaneously.  The simplest thing I found that worked
  on both Windows and Unix was to use the PID.  It's unique so should be
  sufficient.  This should prevent many of the spurious failures of
  the automated tests since they run as different users.

  Also cleanup the directory consistenly in the tearDown methods.

  It would be nice if someone ensured that the directories are always
  created with a consistent name.
