Millised tagajärjed on programmi tööle, kui GOMAXPROCS on seatud väärtusele 1 ja käivitatakse lõpmatu goroutine?

Setting GOMAXPROCS to 1 limits the number of operating system threads that the Go scheduler can use to one thread. In this scenario:

• All computations will be executed sequentially on a single thread.
• If the infinite goroutine does not contain points where a context switch occurs (e.g., blocking calls or runtime.Gosched()), other goroutines may not get execution time, leading to the program "hanging".
• As a result, the program may become unresponsive or run very slowly, since the scheduler cannot efficiently switch between goroutines.

Example:

package main

import (
    "runtime"
    "time"
    "fmt"
)

func main() {
    runtime.GOMAXPROCS(1)

    go func() {
        for {
            // infinite loop without calling runtime.Gosched()
        }
    }()

    time.Sleep(time.Second)
    fmt.Println("Program finished")
}

In this example, the main goroutine may not get execution time if the infinite goroutine does not yield control, which will cause the program to "hang".
