Interesting. I decided to play with this too (on a Lenovo notebook with
two cores, running a 32-bit linux). If I choose to have Mathematica fire
up another kernel "as needed", things run fine. However, if I ask it to
start two kernels "on startup", the Benchmark runs for a long time (I
haven't let it complete yet) and pegs both cores at around 100%. It also
prints no output. Perhaps a bug?
