I'm calling `bytes`, not `str`, what the fuck are you talking about, Python?
Eventually I found `bytes(foo.encode('utf-8'))` which will work in both. I'm
glad I don't use this language any more.

+Had to update SBCL today and wanted to parallelize the build to make it run
+a bit faster. I remember Rainer Joswig tweeting about this but can't find the
+tweet, Googling for `SBCL parallel` is useless, there's no documentation of the
+magic env vars, and I can't find them by scanning `make-config.sh` or `make.sh`
+so I eventually gave up and asked in `#sbcl`. The magical incantation to
+parallelize SBCL with multiple jobs is:
+
+ SBCL_MAKE_PARALLEL=12 SBCL_MAKE_JOBS=-j12 ./make.sh
