Which of the following is most likely to happen when attempting to launch a very large number of goroutines (for example, tens of thousands) without additional control? - The main problem will arise from blocking the global mutex inside the runtime, which will lead to a complete halt of program execution - The Go scheduler will execute goroutines in small groups sequentially, so their number growth has little impact on memory consumption - Mass spawning of goroutines can lead to significant memory consumption and scheduler overhead; in such cases, a worker pool is appropriate - If the number of goroutines exceeds the number of logical processors, Go will automatically start rejecting new goroutine launches with a panic
