Not entirely true.
We have the basic low-level support but the high-level stuff isn't ready for this release (https://github.com/D-Programming-Language/druntime/pull/617).
If you're curious you can try the low-level stuff.
Currently the most accurate howto is the unittests :(, (https://github.com/D-Programming-Language/druntime/tree/master/test/shared).

We need another runtime layer to account for per-thread initialization/finalization of modules (static this()/static ~this()).
There is Runtime.loadLibrary/Runtime.unloadLibrary and rt_loadLibrary/rt_unloadLibrary to do this.
You can use dlopen from a C executable but the loaded D library is only usable from the loading thread.
For a C executable the recommended pattern is to dlopen or link druntime (libphobos2.so) and to use rt_loadLibrary/rt_unloadLibrary to load D libraries.
Currently the best available documentation are the tests (https://github.com/D-Programming-Language/druntime/tree/master/test/shared).
