FWIW it would be wisest to simply copy the code from Mir into druntime 
now with due credit. It's a minimally committal decision than can be 
easily revisited later. It is legal, appropriate, and there's no shame 
to it any more than it is for other projects to fork (parts of) dmd, 
druntime, or phobos.
