Had a quick look at XOmB and XOmB Bare Metal.  It sounds very
interesting, but also very young.  I don't even think they have a
filesystem or moderately complex C application working yet.

I wonder how it performs compared to other C based OSes ??  Probably
hard to compare as it is not a traditional micro-kernel.

I believe that eCos is written in C++ (or a restricted subset), and I
presume that it performs quite well, so given that, I see no reason why
a D based OS/RTOS could not perform as well as eCos or other OSes.
