Here's a more minimal implementation using TLS (but we only have one
thread, the thread checking needs to be implemented as well, but that's
unrelated):
https://github.com/phst/emacs-dynamic-module/commit/41a8cb8a1d29346331fcaf1f28b6c5bee8c8f6ad
This is less than minimal because throw isn't dealt with.
