Just making sure -- is there any way the descriptorSets can be modified before
this command completes on the GPU? (There's a warning about that in the spec.)

Just in the same way the descriptor sets we bind in the above function call can
be changed. We rely on the resource provider to give us a free descriptor set to
use.
