29 I just rebooted. Here's what I see before running any apps:

31 mark@c2stable ~ $ free
32 total used free shared buffers cached
33 Mem: 12303060 462120 11840940 0 12412 178712
34 -/+ buffers/cache: 270996 12032064
35 Swap: 12602976 0 12602976
36 mark@c2stable ~ $

38 It doesn't drop much running Firefox to send this email:

40 mark@c2stable ~ $ free
41 total used free shared buffers cached
42 Mem: 12303060 655776 11647284 0 13824 230160
