That information is all before your eyes. Just follow your patch backwards
to see where the signal you are send~ing is coming from. If the object
you're sending to is _also_ a place where the signal came from (i mean any
signal contributing to what you're send~ing), then you get a
chicken-and-egg dependency. Pd then solves that problem by delaying the
sent signal so that it only has an impact at the next "instant" in the
future, that is, one block away.
