Here's what's going on:
- PyCUDA doesn't currently support recursive launches, which is what's
exposed by the xfail. (This test would start passing as soon as
https://github.com/inducer/pycuda/issues/45 is fixed.)
- The GTX 660i does not support a sufficiently recent compute
architecture to support recursive launches, so this test gets skipped
outright, hence no xfails.
