Finally found the issue! This was caused by passing the
"--disable-threads" option to ./configure when compiling erlang.
Removing the option (the default is --enable-threads) and recompiling
fixes the problem.

One last question: Besides fixing the above issue, I'm a little
confused on what --enable-threads does for me. I see "[async-threads:
0]", so does that mean that even though they're enabled, they won't be
used by default?
