Total time for Node.js time profiles is consistently less than 10 seconds.

Looking through profiles I've collected with the Node.js agent, I've noticed that profiles generally have less than 10 seconds of time.

For example, these profiles only have a duration 8.95s on average:

I would expect that time profiles generally have a duration of 10s when profiling something doing minimal work, and for profiles to be slightly longer when the code is very busy.

What does the duration field contain for such profiles?

The duration field for slightly short profiles is 10s.

Perhaps the function which starts the profiler still has to do some work after it returns but before collecting samples?
