Probably it's obvious but I can't find an answer..
What's the exact meaning of idle in this case? Is there really nothing going on? Or just no JavaScript getting parsed/executed?

The meaning of "idle" is really obvious: "(idle)" means the time spent on doing nothing.
Go to about:blank, and get a new CPU profile. The result is probably a value for (idle) close to 100% and a bit of (program) next question: Chrome debugger - What is "(program)" in the profiler?.
