I'm always getting confused between the French Octets, Bit, and the 
English Bytes and such, so I guess I should have said 4GB ;-) ?

I don't keep a close eyes on my swap, but every time I look at it it's 
not used at all. I guess it depends on the type of use and the apps 
you're running. But from what I read on the subject it seems that 
swapping may occur no matter what settings are used for the swappiness, 
even 0, which is good if RAM is getting scarce...
