We really should fix them. Last year I wanted to get some speed up in patchew's "make check" jobs so I tried this: https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg07713.html On my laptop it can save 50% time as shown in the commit message, unfortunately the patch didn't get enough traction, and I've since then rarely used -j in "make check" command lines (what?!).
