There's been a lot of discussion on-and-off on this subject, and there are
several approaches using coroutines that work fairly well. One that I
played with a little bit was a simple scheduler written in Lua that can do
some of this. Check:

Having said that I should warn you that I am NOT a game developer. I wrote
this as a way of scripting simulations. I *think* it will work well for
games.
