Is that generally the case on your systems? Every linux system I've
run, regardless of RAM, has always pushed things out to swap.

For me, it is generally the case yes. We are still discussing this in the context of desktop machines and their problems with being slow as things have been swapped out and generally I expect a desktop to have plenty of swap which it's not regularly going to fillup significantly since then the machine's unworkably slow as a desktop anyway.

And once there's something already in swap, you now have a packing
problem when you want to swap something else out.

Once we're crammed, it gets to be a different situation yes. As far as I'm concerned that's for another thread though. I'm spending too much time on LKML as it is...
