Agreed. While not a full solution, I think this patch is still good to
address some of the pain: Waiting 10 seconds at the end of my build
with only 1 of my 10 cores doing anything.
So while this doesn't decrease CPU time spent it does decrease
wall-clock time significantly in some cases, with afaict no downsides.
