StartTheWorld restarts the world after it was stopped by StopTheWorld.
func StopTheWorld(reason string)
StopTheWorld returns with the world stopped.
Current goroutine remains the only one who is running, with others goroutines stopped at safe GC points. It requires careful programming as many things that normally work lead to fatal errors when the world is stopped - for example using timers would be invalid, but adjusting plain values in memory is ok.
