hi brad, what kernel version you was using? anyone know if the new 3.9

anyone know who control the swap? or what source files should i look
to understand swap better?

Back then it would have been 2.2 or possibly early 2.4.
Can't really help with the other questions. I still have large amounts 
of swap on all my machines for historical reasons, however it rarely 
gets touched and certainly not intentionally.

I find it much nicer to be able to deal with performance issues caused 
by a runaway processes forcing stuff into swap than it is to deal with 
"random" processes being shot by the OOM killer.
