/ Overall, the philosophy is to attack    \
| the availability problem from two       |
| complementary directions: to reduce the |
| number of software errors through       |
| rigorous testing of running systems,    |
| and to reduce the effect of the         |
| remaining errors by providing for       |
| recovery from them. An interesting      |
| footnote to this design is that now a   |
| system failure can usually be           |
| considered to be the result of two      |
| program errors: the first, in the       |
| program that started the problem; the   |
| second, in the recovery routine that    |
| could not protect the system.           |
