Is there anyway one kernel thread can switch between compute intensive tasks?

Is your equivalent in Go using Printf in the loop? I don't know the Go 
runtime but that is one possible place for a kernel thread to yield. 
There is also the GOMAXPROCS variable to control the number of kernel 
threads that run concurrently.
