[flexcoders] Execute events while loop is iterating - possible?

[Baz]

If I have a FOR loop that dispatches events, is it possible that those
events will be acted on before the loop finishes? For example:

FOR LOOP BEGIN 100000 ITERATIONS
     DISPATCH EVENT TO CHECK A CHECKBOX
FOR LOOP END

In the previous pseudo code, lets say the logic in each iteration is very
long and complex, is it possible that some checkboxes get checked before all
100000 iterations are complete?

Cheers.
