This patch tries to make sure that the vbl.reply.sequence vblank count for a queued or emitted vblank event always corresponds to the true vblank count of queueing/emission, so the ddx can rely on the returned target_msc for consistency checks and implementation of swap_intervals in glXSwapBuffers(). Without this there is a small race-condition between the userspace ddx queueing a vblank event and the vblank counter incrementing before the event gets queued in the kernel.
