Looking at the output of "sysctl -a" on a now almost idle machine I see:

ITEM            SIZE     LIMIT     USED    FREE  REQUESTS

~ [ .. ]

ata_composit:    192,        0,  12296,    124,    62341
ata_request:     200,        0,  24592,    108,   920945

~ .. shouldn't these be freed at some point if there's minimal disk
activity (and few dirty buffers, "systat -vm" says there are 7)? Or am I
misreading this?
