FYI, we're investigating a pretty big regression in Rust when built with LLVM containing this change. I don't have much yet, but

  io::buffered::tests::line_buffer_write0_normal
  io::tests::chain_zero_length_read_is_not_eof
  io::tests::read_exact
  net::tcp::tests::timeouts
  net::udp::tests::timeouts
  os::unix::net::tests::timeouts

in library/std tests are all broken by this change. I'm working on getting something more now.
