In order to make the full stack in D, I think we eventually will 
need to make 2 toolchains: a bare-metal kernel toolchain, and an 
application programming toolchain.

The bare-metal kernel toolchain would not have some of the 
high-level features of D, like threading and synchronization, as 
that has yet to be built.  However, once a D RTOS is created with 
all necessary features for theading and synchronization, then the 
application programming toolchain can be made with a druntime 
ported the D RTOS's API.

I've also considered another interesting approach.  It seems 
possible to port all features of D right to the metal, 
essentially embedding the RTOS directly into the runtime.  Then D 
is your RTOS :-)
