I believe if we limit the unpacking process to not more than 8 cores we
can avoid that problem.

Keeping this to i686-linux specifically, what generation of hardware
supports i686 but not x86_64? Some (very) quick checking on wikipedia
suggests that the x60 from 2006 was either 32-bit or 64-bit, and I
believe there was an atom chip from 2015 that was 32-bit. Specifically,
that makes the newest hardware (at least from the CPU perspective) 10
years old at least.

Perhaps a different question, what software _available in Guix_ is
supported by i686 that isn't supported by x86_64?

In terms of side-stepping the question, do we have enough x86_64
hardware to continue to support i686 without degrading support for
x86_64? (I ask this seriously, although I'm pretty certain the answer is
we're well covered on that front.)
