it's a bug to assume anything about the order of execution when it comes
fan-outs happen, when you explicitly connect a single (message) outlet
to multiple inlets.
fan-outs also happen with implicit connections between a single [send]
and multiple [receive]s.
the order is undefined (and it's up to the implementation how it
eventually turns out; and the implementation is free to change its
current behaviour *at will*).
if you must use [send] with multiple [receive]s, you must write your
patches in a way to make them resilient with respect to the order of
