i'm not sure i follow, but i'll probably need to take some time to think about your response in order to ask some relevant follow-up questions. one thing i don't understand is why the script is run "over and over" vs starting it once and letting it run.

in the meantime, have you looked at or considered co-processes/co-routines?

if you're not familiar, here are a few older pages related to the topic...
