Trellis-based frametype decision doesn't actually require any particular threading model; it only requires that you have frametype decision totally separate from actual encoding and motion estimation, so that you can do the former however you want without affecting the latter. I don't recall off the top of my head if Xvid uses x264-style lookahead or lavc-style lookahead (the latter being the one where the encoder uses the same motion estimation for both frametype decision and actual encoding).
