    Ah, very nice, I somehow missed it.

    I guess one issue is that explicit sync isn't quite plumbed through
    compositors yet, so without Jason's DMA-BUF to sync_file IOCTL it'd be
    a bit difficult to use.

    Can anybody set the deadline? I wonder if clients should be allowed to.

    What happens if the deadline is exceeded? I'd assume nothing in
    particular, the deadline being just a hint?
