This sounds like a job for the new coroutine features in 5.0-work0 --
you can put a "yield()" call in your scripts where you want to return
back to the engine, and the engine can call "lua_resume()" when it
wants to continue running the script from the spot where it yeild()ed.

In the example above, you could replace "man_wait()" with "yield()".
