Well, pre6aa1 performs really badly exactly because it by default doesn't
swap enough even on _normal_ loads because Andrea is playing with some
tuning (and see the bad results of that tuning in the VM testing by
[e-mail]).

So the pre6aa1 numbers are kind of suspect - lack of swapping may not be
due to fixing the problem, but due to bad tuning.

Does plain pre6 solve it? Plain pre6 has a fix where a locked shared
memory area would previously cause unnecessary swapping, and maybe the CD
burning buffer is using shmlock..
