Thank you for sharing that.

`guix build --no-substitutes --cores=1 --max-jobs=1 webkitgtk`
`sudo guix system --no-substitutes --cores=1 --max-jobs=1 reconfigure 
configuration.scm`
These two commands fail to build webkitgtk with the error message
reported previously.  The problem being what you have identified (using
one core).

`sudo guix system --no-substitutes reconfigure configuration.scm`
Fails to build webkitgtk because of what looks like an out of memory
issue.  With "oom_reaper" showing up in /var/log/messages.

`sudo guix system --no-substitutes --cores=2 --max-jobs=1 reconfigure 
configuration.scm`
This command was successfully able to build webkitgtk.
