/* eCOS also has a CPU load-monitoring facility that we could in theory
use as a source of entropy but this is really meant for performance-
monitoring and isn't very suitable for use as an entropy source. The
way this works is that your first call a calibration function
cyg_cpuload_calibrate() and then when it you want to get load
statistics call cyg_cpuload_create()/cyg_cpuload_get()/
cyg_cpuload_delete(), with get() returning the load over a 0.1s, 1s,
and 10s interval. The only one of these capabilities that's even
potentially usable is cyg_cpuload_calibrate() and even that's rather
dubious for general use since it runs a thread at the highest priority
level for 0.1s for calibration purposes and measures the elapsed tick
count, which will hardly endear us to other threads in the system.
It's really meant for development-mode load measurements and can't
safely be used as an entropy source */
