If you are talking about events and all that, I suppose you are using
(or should be using) threads.

Why don't try running the length_function as  a Thread that on every
loop checks a semaphore and if the condition is met, exits itself?
Kinda like this:

PS: Note the "try..." in my reply. I've never done this, so I'm not
sure it's going to work. Wiser people in the list will probably give
you better replies.
