I see. I guess it would not have helped in my case as it was, since the |

problem was due to another user's process blocking the IO, and I am not |
| 10 |
root on my work machine. |

A young woman was jogging when she saw a wizened old man, smiling at her |
| 30 |
from his porch. |
| 31 |
"You look so happy!" she said to him. "What's your secret for a long |
| 32 |
satisfying life?" |
| 33 |
"Well, I smoke three packs of cigarettes every day and I drink a case of |
| 34 |
wisky every week. on top of that I never excersice, and I eat lots of |
| 35 |
fatty foods." |
| 36 |
"That's amazing," the woman said. "And how old are you?" |
| 37 |
He answered, "thirty two." |
