Understanding goroutines

Question

I\'m trying to understand concurrency in Go. In particular, I wrote this thread-unsafe program:

package main

import          


        

Answer 1

No sure, but I think that inc_x is hogging the CPU. Since there's no IO it doesn't release control.

I found two things that solved that. One was to call runtime.GOMAXPROCS(2) at the beginning of the program and then it'll work since now there are two threads serving goroutings. The other is to insert time.Sleep(1) after incrementing x.
