<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>
