Turns out it's impossible to use generic newtypes across crates:
test.rs:
pub struct Foo<T>(T);
impl<T> Foo<T> {
pub fn new(t: T) -> Foo<T> {
Foo(t)
}
}test2.rs:
extern mod test;
use test::{Foo};
struct Baz;
fn main() {
Foo::new(Baz);
}~ ❯ env RUST_LOG=rustc=1 rustc -L. test2.rs

error: internal compiler error: unexpected failure
note: the compiler hit an unexpected failure path. this is a bug

This makes it impossible to use std::rt::io::buffered::BufferedStream.
