Cool I didn't get the chance to take a look at it before. I'm using it now. I noticed that the line:
time make -k test >> "$logfile" 2>&1 || true

doesn't use the -j option for make. I'm not sure if this is intentional, but when I changed it to
time make -j"$(nproc)" -k test >> "$logfile" 2>&1 || true

it ran much faster. Thoughts? Am I just breaking something without realizing it?
