In its current implementation, it uses mutexes (or did last time
I checked). However, this isn't required.

I wanted to implement something a while ago, but was stopped by
the fact that DMD doesn't implement shared as per spec (ensure
sequential consistency). It is still possible to do with
primitives for concurrency available in the runtime.

If you plan to submit a pull request, I'll be happy to review.
