Hyper-threading

[Steven Hartland]

IIRC you dont see an explicit start for CPU #0 as its the one
running the boot sequence :)
You can use systat, top -S, ps -aux or sysctl to check for the
number of processors. look for the number of idle processes
in the first three and for either kern.smp.cpus or hw.ncpu
the sysctl.
