yes
What operating system and processor architecture are you using (go env)?

What did you expect to see?
I read the source code, and then find: the last line is the num of goroutines which are created before trace taken, and inactive during the trace.
I think may add a name/desc to it, like: inactive when trace.
in httpGoroutines func add:
and then see:
What did you see instead?
