Race condition creating buffers

[ccummingsNV]

During testing, I found that calling the following:

            render_data.index_buffer = self.device.create_buffer(
                usage=sgl.ResourceUsage.shader_resource,
                debug_name="index_buffer",
                data=np.copy(mesh.indices),
            )

Could result in a permanently corrupt index buffer. The only way to fix it was to call device.wait() immediately before the buffer setup. The issue reproduced itself when creating around 150 index/vertex buffers.
