According to Python documentation here for execvp: http://docs.python.org/2/library/os.html "The current process is replaced immediately. Open file objects and descriptors are not flushed, so if there may be data buffered on these open files, you should flush them using sys.stdout.flush() or os.fsync() before calling an exec* function.
Without the flush, we will miss the print statements before that if we redirect the o/p to a file.
