>From the hacked thinkpad X201 I'm typing this on:
% cat /dev/swap
68491845632 memory
4096 pagesize
524288 kernel
1343866/15661303 user
0/320000 swap
23811/15661303 reclaim
54772160/55446976/2147073280 kernel malloc
72373216/72834080/1932365952 kernel draw
3296/65568/16777216 kernel secret
It's excessive, but that's what it came with; it's occasionally
useful for VMs in VMX. The machine was purchased before the
current shortages.
