I have identified some problems with the threading code and the
ConfigureAndWatchThread itself. I think I have fixed at least one related to
the life time of the watch dog thread object. To get it check out the code
from
<https://log4cplus.svn.sourceforge.net/svnroot/log4cplus/branches/PRODUCTION_1_0_x/log4cplus>.

To work around the problems in the log4cplus code, try the following instead:

ConfigureAndWatchThread * configureThread
  = new ConfigureAndWatchThread(LOG4CPLUS_TEXT("logger.properties"), 5 * 1000);

delete configureThread;
sleep (5 * 1000 + 1000);

The problem here is that right now there is no way how to reliably wait for
the watch dog thread to exit before exiting main().
