 Good question. I just repeated the execise, rebooted and
 copied a 700MB file. After ~30min "Dirty" is down to ~130MB, and
 continues to decrease very slowly.

 On my Desktop machine (P4 HT, 1G RAM) "Dirty" goes down near
 zero after ~30sec, as expected.

Are you using any unusual mount options?

Which filesystem types are online (not that this should affect it...)
