How should I interpret the statement the bullet point stating "Ability
to layer this libc over the system libc"? If this project does not
consider Windows support (e.g.) out of the box, I worry we will design
ourselves into unsupportable use cases. It's not that I want to commit
anyone to supporting other platforms right out of the box, but LLVM
supports non-ELF targets and so whatever we wind up with as a design
had better also support non-ELF targets and I'm not confident that's
the case here.
