Sorry about the empty email, I've hit send too fast… Anyway, on the topic of parallel builds: what is everyone's opinion on adding the %limit_build macro from openSUSE (see: https://build.opensuse.org/package/view_file/network:chromium/memory-constraints/memory-constraints.macros?expand=1)? tl;dr; %limit_build -m 1500 will set the number of parallel processes so that if all of them consume 1500 MB of RAM at most, that they will not OOM your worker (especially handy on workers with many cores, but not much RAM).
