Maarten, I'm finding fairly little out there on what threaded-ml might be. What I do find suggests 3D visualization and real-time audio playback. Are you working with something like this? If so, which libraries are you using? If not, any idea what this is?

Maarten, could you provide the addr2line of the addresses from do_futex to spin_bug ? This will help me trace the path.
