        <pre>Hmm. Hangcheck looks healthy enough. Our survival is dependent on

                igt_until_timeout(20) {
                        for (i = 0; i < nhandles; i++) {
                                igt_spin_free(fd, spin[i]);
                                spin[i] = __igt_spin_new(fd,
                                                         .engine =
engines[rand() % nengine]);
                                handles[i] = spin[i]->handle;
                                __sync_synchronize();
                        }
                        count += nhandles;
                }

not blocking and killing all handles every 6s (or hangcheck frequency).

And nhandles is gem_measure_ring_inflight(). Ok, I think this is another
off-by-one due to the ring wrapping.</pre>
