Exactly. This is not an option. > After looking into the Maxima code a little more, I doubt what I said > about --readline-off is true.

Does anyone no of any test cases now for Maxima > that seem to fail due to the communication between Maxima and Sage? Maxima should never ever fail due to communication between SAGE and Maxima. I spent a lot of time making sure of that a few months ago, when we were rolling out the calculus functionality, which uses the maxima interface very very heavily. When you doctest the SAGE_ROOT/devel/sage/sage/calculus directory, there are literally hundreds of different and subtle interactions between SAGE and maxima via the interface -- some involving expecting interactive questions about input, etc., and it all happens very very quickly, but it works perfectly every time now. It just took a lot of work refining how the maxima interface works -- it resynchronizes itself before every interaction by putting "random number + 1" in the input and waits for the result of that arithmetic, etc. I'm sure the axiom interface could do something similar.
