Maybe multithreading is just not yet implemented?

I could see ClojureC being very useful for when you want:

  * small footprint
  * easy C-library interop
  * fast start-up time

and where you don't necessarily need multithreading.

(BTW, I'd be curious to hear what you think might be the differences in use cases between ClojureC and mjolnir/clojure-metal.)
