Since no one else has mentioned it yet, let me present, The Barrelfish
Operating System:
http://barrelfish.org/
As described in this paper:
http://barrelfish.org/barrelfish_sosp09.pdf
"We investigate a new OS structure, the multikernel, that treats
the machine as a
network of independent cores, assumes no inter-core sharing at the
lowest level, and moves traditional OS functionality to a distributed
system of processes that communicate via message-passing."
This paper describes the use of DSLs and DSL -> C compilers written in
Haskell to generate low-level kernel code:
http://www.barrelfish.org/fof_plos09.pdf
The aim is to be able to build provably correct DSLs and compilers
fast enough that you would actually prefer to use them as part of the
development process instead of just doing the low-level C code by hand.
