It is amazing how difficult it is to get non-programmers to understand the affect interruptions have on the art of creating a program. A 10 second interruption really means 30 minutes of vastly decreased productivity, as it can easily take that long to reload a programs universe back into your head.
More often than not, the reload is imperfect and parts of the universe are not restored, leading to more lost productivity as the programmer must recreate the solution they already had worked out. Another subtle side-effect of this imperfect reload are bugs caused by a mismatch between the pre and post-interruption program state.
