I'm having a slight problem using wait3 or wait4. I want monitor a launched process and get its resource usage information. When I call os.wait4 with the pid the first time the call returns successfully but the second time around I get a OSError with "No child processes" error. I have tried using WCONTINUED, WNOHANG and WUNTRACED options. Sunil. -- http://mail.python.org/mailman/listinfo/python-list
