This will be very useful when doing huge computations again of which I want the output logged and also want to check on the progress from time to time. Note for the non linux users. To deal with this particular use case we could also use any of the solutions as found on http://stackoverflow.com/questions/107705/python-output-buffering The environment variable solution will work out of the box with sage also. Maybe -u mentioned there would also be a good command line option for sage.
