In this case I don't think it is anything to do with
pkg_rolling-replace; I've reported a few of these hangs, which happen
to happen during pkg_rolling-replace, but involve most often cmake,
but other programs as well. Apparently there are similarities in the
traces, perhaps pointing to the thread model and execution. In all
these occasions the process in question continued to a successful
conclusion after attaching and then detaching with gdb.
