swappiness ignored

[Anthony DiSante]

In the "why swap at all" thread, there was mention of the 
/proc/sys/vm/swappiness tunable, and some people suggested echoing a zero to 
there if you want to minimize/disable swap usage, or echoing a 100 to 
maximize swap usage, etc.

But on my 2.6.5 system, I can echo a zero to there, then cat it back to make 
sure... then 30 seconds later cat it again, and it's been changed to 
something else (50, 60, 80something).

Is this supposed to be a value that can be manually adjusted, as some have 
claimed, or is it something the kernel manages automatically?  I definitely 
can't manually set it without having it overwritten shortly thereafter.
