[R] bam (mgcv) not using the specified number of cores

I am getting strange behavior when trying to fit models to large
datasets using bam. I am working on a 4-core machine, but I think that
there may be 2 physical cores that the computer uses as 4 cores in some
sense that I don't understand.
When I run the bam using makeCluster(3), the model runs on one core.
But when I run it on makeCluster(2), top shoes me that three of my cores
are taken up to full capacity, and my computer slows down or crashes.
How can I get it to truly run on 2 cores?
I'm on a thinkpad X230, running ubuntu.
