But that wasn't true either at the time of Go 1.1, nor ever I believe. It was the _default_ behavior to have a single core running at a time, but you could just tweak that with the [GOMAXPROCS](https://godoc.org/runtime#GOMAXPROCS) variable, documented everywhere. (That's what changed in Go 1.5; now the default for GOMAXPROCS is the number of cores in the machine.)
