I can't tell you that for sure - you would need to test it. However, the
fact it has used 67 minutes of CPU time, but took 37 minutes to build,
suggests the parallel build is working. I doubt any overhead could explain
that difference.
That should be quite useful, as Singular is probably in the top 3 of
packages taking the longest to build. In fact, it might have the !#1 spot.
So it's worth making Singular work in parallel, whereas for some packages,
it's hardly worth the bother.
