### How much cpu time in ulimits?

You can set the cpu time using ulimit, but to what?
On our 4 quad-core machine, we have set the soft limit to 80 minutes (4800 seconds) but allow the user to increase it to up to two days. On our company wide file server it is set to 20 minutes (1200 seconds).

### Latex: Centering table larger than textwidth
