No. Cancellation is not defined as completion. Iterating over the ports
and then calling complete that only operates on the first port and
doesn't even take the port as implied by its name is horrible.
Just a patch moving the cancellation to its own function that doesn't
need to be inlined since it is called only on reset is what I want to
see.
