At some point I'll replace the comments with something shorter and written in my own style. I didn't want to do that originally mostly because I didn't want to claim authoritatively the system states that are described in the comments for the different callback functions that I filled in with my own code.

I'm still curious what's accounting for the load average being higher than I'd expect when there are 2 running/computable processes and 2 CPUs. I'd expect to see values closer to 2.0 than 3.5 to 4.0. At least it shows ~0.01 when idle. It looks to all appearances like a running process can show up as computable and also current on a CPU, including in the MONITOR system process counts. Not that this is the sort of thing that a hardware device driver would ever be concerned with, as opposed to a pseudo-device driver that's poking around in the system state.
