Description kavol 2021-03-19 20:19:25 UTC 
in todays updates, there was llvm

during build, my machine got low on resources, so I've switched to konsole running the emerge and hit ctrl+z

I got the usual message about process being suspended

[1]+  Pozastavena             emerge -avuDN --with-bdeps=y --backtrack=30 --keep-going world

however the system was still under heavy load making it unusable for the next few minutes ... looking at top, there were many compiler processes running, and new processes kept spawning even after some files finished compilation

Reproducible: Always

Steps to Reproduce:
1. # emerge llvm
2. hit Ctrl-z
3. # ps xfa
