Number of OS threads used by Go runtime

Hi all!

Is there any way to count number of OS threads used by Go runtime programmatically (ie without using bash with top/ps and others)?

Not at present.

Perhaps it could be added to the SchedStats proposal

I suggest to give n, _ := runtime.ThreadCreateProfile(nil) a try.
