radeonsi currently allocates very small BOs (8-32 bytes) for T# descriptors, and throws them away immediately after drawing. That alone of course is insane under a performance aspect, but waiting for the last job to finish makes things completely worse. It just moves my priorities of hacking on radeonsi a bit around.
