And, just to be clear, CPU_Time corresponds to the "awake time"?

I thought I understood pretty much what was intended in the execution
time annex, even if it didn't seem to have much relevance to my work,
but this discussion has managed to confuse me thoroughly.

A minor aside -- as a user, I find the use of Time_Span here and in
Ada.Real_Time very annoying. It's perfectly clear that what's meant is
Duration.
