=======
TimeoutInterruptSingleton created for helper methods like setup and so on.
TimeoutInterrupt#timeout and TimeoutInterrupt.timeout are stubs for calling timeout of singleton-class.
Scopeable
=========
`TimeoutInterrupt.timeout` should be scopeable now.
`TimeoutInterrupt.timeout` without args will check timeouts and will raise the next timed out timeout,
needed for scopes and if many time outs at the same time occurs.
