 * Note: there's a known issue with this program double closing the
 * test file pointer.  This is because the test shares the file with
 * the log4c stream appender and they both close it on exiting.  In
 * the context here this error is benign. The stream2 appender
 * does not have this issue as it will not close a passed-in
 * file pointer on exit.  In general you would not share a file pointer like
 * this with an appender so that behaviour of the stream appender is not a
 * serious issue.
