Again, skip 'all' since we'll have one per actual CPU.

perhaps add "starting from zero" to convey they are numbered 0, 1, 2 and
so forth.

Uh, this I don't like, it will be too difficult for programs to parse.
Perhaps
just punt it until now? Note that I'm going to add a stringlist property
to
HEAD somewhat soon (will be used for info.capabilities instead).

Rather, the _maximum_ speed of the processor.
