Don't forget that Axiom runs as a lisp application (GCL). This means memory allocation is dynamic and that memory usage can be affected by when lisp decides to do garbage collection. You can force GCL to do garbage collection and return unused memory. Try using the command: )lisp (gbc 3) after the )undo -2 On my Windows version of Axiom this returns some memory to the operating system. I don't have the linux version here right now to try this. Please let me know what you get.
