I can tell you what the code is trying to do, though not necessarily why
it's failing for you. It is waiting for its parent process to die. It is
checking every 50 milliseconds for that to happen. I'd guess that either
its parent isn't dying (getppid never is equal to 1) or your OS doesn't
exhibit that exact behavior, or the init process isn't process ID 1. You
might try to spin a little slower ( 'select(undef,undef,undef,1.0)...')
and spit out what getppid is prior to the undef and within the loop
itself.
