I don't remember how it is on DragonFly, but most MP-able Unix systems
have it included as a column in "top". You may need to use some
options, as it's not part of the standard for top.

I haven't seen a top that refines it down to which threads are on
which processors, but in fact, I think the top in modern Linux
distributions does that with the right options.
