Before:

 time ./tools/genboardscfg.py
Generating boards.cfg ...  (jobs: 32)
1177/1177 [=======================================================>]

real 0m27.018s
user 7m15.330s
sys 2m57.488s

After:

time ./tools/genboardscfg.py
boards.cfg is up to date. Nothing to do.

real 0m0.278s
user 0m0.199s
sys 0m0.079s

rm boards.cfg
time ./tools/genboardscfg.py
Generating boards.cfg ...  (jobs: 32)
1177/1177 [=======================================================>]

real 0m8.607s
user 3m9.580s

Wow, nice work!
