Well, dfsch is currently not work in progress, because there is no meaningful progress :) But it was originally intended as scheme interpreter with native threading without GIL. Last version has GIL-style global lock, but interpreter threads can run user code without ever acquiring that lock. (In essence: the lock protect structures that cannot be proven to not be shared between threads, which are not required to interpret output of dfsch's compiler for most inputs)
