Re: Performant?
Interrupts are very heavy weight on the Multics hardware; the emacs' interrupt-per-character paradigm was rough on Multics. Later enhancements to the front end processors allowed buffering of characters and greatly reduced the impact of emacs. Also, the simulator has several times the performance of the original h/w, and everybody can afford to have there own personal Multics system.
