Thanks for the response Jeff ... but the example you linked is very similar to what I have ( in another codebase ) that works. ie I don't have problems with this method when *forking* a process - it works really well. I have problems with this method when I want to tail ( or use Glib::IO->add_watch() on ) STDOUT & STDERR of the *current* process.
