"Program development generally occurred out-of-hours," a programmer subsequently explained to Salus.

This allowed others to save their editor-files quickly (and often)."

We went to lunch afterward, and I remarked to Dennis that easily half the code I was writing in Multics was error recovery code. He said, "We left all that stuff out. If there's an error, we have this routine called panic, and when it is called, the machine crashes, and you holler down the hall, 'Hey, reboot it.'"
