<pre>Interesting... so this may actually be a legit situation of "gpu not processing
pushbufs fast enough" and we run out of IB space. For some reason each pushbuf
has a very small quantity of commands... oh, I see. It's just a ton of
small-ish indexed draws, each of which ends up going through
nouveau_pushbuf_data() which in turn causes a new IB slot to be used up.
We need to have some way to figure out how many IB slots are open... or
throttle pushbuf submission or... something.</pre>
