Actually, libcdparanoia is sitting in an infinite loop, getting
errors from the device and blindly retrying.  It's a bug in
libcdparanoia.  Unfortunately, it's not easy to fix -- it basically
requires pulling libcdparanoia's API out of the stone age.

Yes, but imo it would be smarter to add such capability to GStreamer,
not individual elements.

That would be the best solution right now (for catching all
infinite loop bugs).  Next best, the cdparanoia element should
have its own watchdog, since it has known issues with infinite
loops.
