The number of threads in syscall presented by execution tracer's trace view includes not only the threads calling system calls on behalf of user created goroutines, but also those running on behalf of system goroutines. When the number of such system goroutines was small, the graph was useful when examining where a program was saturating the CPU. But as more and more system goroutines are invloved the graph became less useful for the purpose - for example, after golang.org/cl/34784, the timer goroutines dominate in the graph with large P because the runtime creates per-P timer goroutines. This change excludes the threads in syscall on behalf of runtime (system goroutines) from the visualization. Alternatively, I could visualize the count of such threads in a separate counter but in the same graph. Given that many other debug endpoints (e.g. /debug/pprof/goroutine) hide the system goroutines, including them in the same graph can confuse users.
