I have two processors, so I tried to run it on one, and it worked:

```
root@watson ~# time guix pull --cores=1

Right now I'm updating packages, and things are looking up.

Do you have any idea what went wrong when using both cores?

I am conflating cores and processors right now.  I think these are
equal for this system, but I'm not sure.  I have an Intel Core2 Duo.
/proc/cpuinfo shows two processes.  Furthermore, I presume that
`--cores N` actually means that guix spawns N processes.
