I tend to agree with that basic philosophy. From other items in the
thread, it was clear this came up in the context of build release,
which benefits from -j usually. The installworld phase in that should
be as robust as possible as well, since otherwise we have issues with
the actual release. Unless it is a big win (more than a few percent),
I'd imagine the right fix is to the release target to not do a
parallel installworld. I know that in the build scripts that I wrote
in 3.x days and have ported forward since then I've never done a
parallel install, due to it rarely working reliably in that (long)
time span...

They are safe to do nowadays. I'll do some measurements on real
SMP with the memory-based DESTDIR, and let you know the numbers.
