On Linux/x86-32, the default stack size for a new thread is 2 mb. The default stack for a goroutine is 2 kb. Those 1000 goroutines eat up as much memory as roughy one OS thread. Granted, I've somewhat shifted the goalpost, but goroutines are cheaper than OS threads or just about every sensible definition of "cheap".

    Your general point does not stand. It is totally incorrect. A thread does not commit its stack limit immediately. The limit is the limit. The initial size is a single page.

      And even then, the original point wasn't "an OS thread is as cheap as a userland thread", it was "all things considered a native thread is pretty cheap".

      You misunderstood the point.
