I know, but what I am trying to say is I don't know how to compute a "big
total" memory usage needed before hitting swap. No matter how I add, the
final number is not in the line with the dmesg reported memory. Here is top:
$ top
load averages: 0.33, 0.23, 0.10 thinkc.my.domain
12:20:39
47 processes: 46 idle, 1 on processor up
4:17
CPU0: 22.4% user, 0.0% nice, 3.8% sys, 0.6% spin, 0.6% intr, 72.7% idle
CPU1: 21.2% user, 0.0% nice, 3.0% sys, 0.2% spin, 0.0% intr, 75.6% idle
Memory: Real: 1235M/2914M act/tot Free: 4505M Cache: 1054M Swap: 0K/7913M
