I had an emerge process running. I use EMERGE_DEFAULT_OPTS="--jobs 4 --load-average 8" so a parallel ebuild was happening, but only one package (Firefox) was actually being built at that time. I needed to temporarily free up RAM and CPU for another task, so I pressed Ctrl+Z. Portage itself suspended and gave me back a Bash prompt, but half an hour later, rustc and cc1plus processes were still running according to top; it looked like the SIGTSTP was prevented from reaching the underlying compile process at some point. Reproducible: Always Steps to Reproduce: 1. Start building www-client/firefox. 2. Press Ctrl+Z. 3. Run top. Actual Results: rustc and cc1plus processes doing work Expected Results: System idle, no CPU being used $ emerge --info Portage 3.0.8 (python 3.7.9-final-0, default/linux/amd64/17.1, gcc-9.3.0,
