When a behavior or compose block of a modular scenario executes for a long time without yielding control, there is no way to tell whether it has entered an infinite loop with no take/wait statements, or is actually doing some long computation. But since forgetting a wait statement in a while loop is an easy mistake, we raise this warning after a behavior/scenario has run for `stuckBehaviorWarningTimeout` seconds without yielding. """ pass
