Kapps in #d freenode suggested the problem is in the allocator 
not having registered

This worked!

However, we now have problems when shutting down.

It appears that during garbage collection, a call to 
core.thread.suspend() throws the following exception:

>throw new ThreadException( "Unable to suspend thread" )

Which results in an infinitely recursive loop, where the 
allocator continuously tries to throw exceptions!

I think perhaps I need to give D the opportunity to clean up 
SDL2's audio thread before shutting it down?
