To see how much overhead does the SMP support in kernel bring, as
compared to the UP kernel. There's a relatively big difference in how
internal scheduling and synchronization works in these two cases.

The purpose of the benchmark is to show if, in the long term, the SMP
kernel could be made the default one.
