I can recommend using LMDB[1] which likely does all you want.
It also has D bindings[2]. We use it in the AppStream generator 
with multithreaded parallelization and it is working great so far 
(although for the usecase of asgen it's not an ideal database 
choice, but one which makes deployments of the generator really 
simple).

I explored other solutions including Tokyokabinet and LevelDB and 
LMDB was by far the fastest.
