script works only during debugging

[Bob Sneidar]

Think of script execution like a slide at the playground. Only one kid can go down the slide at a time, and each kid has to get off the slide before the next kid can go. However you can queue up kids on the platform at the top. You can even tell one kid to go before another that is already on the platform, because the platform at the top of the slide is big enough to hold a number of kids. 

Okay, the analogy is getting out of hand. So if you had send in 2 seconds followed by send in 0 seconds, the second one would go first IF it happened before 2 seconds was up. Otherwise it would go second because it was queue'd second and the first send's time delay already expired. See? 

Of course, my normal disclaimer of, "I might be wrong about this" applies here, but I think this is how it works. In the final analysis, only use send in time if you need a handler to fire after the first is done. Otherwise just call it in line after whatever needs to happen first has happened, and let the single threading of the LC engine keep things orderly for you. IMHO of course.
