Did you apply Con's disable-swap-token leaving the sysctl to the default
value after applying that patch?

Of course I know if you don't apply Con's fix it will run oom, you don't
need a cp for that.

The process 'dd', and all the other processes, live in
the highmem zone, which has 2.5GB of memory free. Now
tell me again why you think the swap token has any
relevance to those 950MB of pagecache that is filling
up lowmem ?
