Don't forget that the system also pages to swap space and it takes the
attitude of parking as much as possible out there in case it comes in
to demand again.  Ten if it really needs the space for something, it 
invalidates the oldest stuff and uses that space.

So, you should really expect that your swap space should be 
nearly maxed all the time if things are working well.

Someone else can give you more accurate detailed information
if you want it.
