- The keyboard is an interrupt. Whenever you press a key, control jumps
- to the interrupt handler. That's why Ctrl-Alt-Del almost always works.
- In DOS, a program can write their own interrupt handler. In OS/2, a
- protected operating system, IBM could write a more robust interrupt
- handler, like their Ctrl-Alt-Del one that allows killing processes
- (including the WPS, hopefully)
