These are good answers, thank you...

On the subjects of signals, my intent is to be able to use signals to 'signal' my daemon app to do a clean shutdown; or for logrotate to notify that the logfile I am watching has been rotated.

My testing has shown that once my main thread drops into a 'join', signals are no longer processed. That would make 'join()' non-interruptable. In place of that I am trying: 

 #done starting all threads

 while (!$cleanShutDown) { # set in SIGHUP handler
    sleep 30;  # which is interupted by a signal
 }
 $logmon -> join();
 ... #more joins
 exit 0;
