Yes, I am not chuffed in having it. But with the transition from using
an array of execobj[] to having a list that includes the supplementary
objects, the inplace swap() now breaks the lists. We would have to do a
bunch of list_replace() to preserve them. At the moment, I think this is
the lessor of evils, although it is quite hideous.
