Yeah. I am going to add a config parameter to the buildfarm to allow
parallelism for the "make" and "make contrib" stages, but I'm not going
to release it until this is fixed.
(I suppose this is also a lesson to me that I should not ignore things
like this that annoy me persistently as I did with these failures until
Robert Creager started this discussion. It just didn't seem important
enough.)
