This is the type of JavaScript problem that has caused me a lot of
problems ... and made me discouraged about building a better/more generic
event notification between Jmol and JavaScript.

You certainly do not want to do this ... it looks like to me that this is
essentially an infinite loop ... calling setTimeout a huge number of
times. Each time you call setTimeout it returns immediately, but it has
queued a call to check() 100 ms in the future.
You only want to call setTimeout one time.

I don't think that you want to do it this way.
I don't think you want to think of it as 'waiting' until the script
completes.
Rather, I think that you want to restructure it and think of it as 'run
this function when the script completes'.
But I cannot give you any specifics because I do not have a lot of
JavaScript programming experience.
