Since the introduction of debugfs/i915_drop_caches, we have offered the
ability to wait upon all outstanding batches. This is more efficient and
less error prone (one example is the use of context priorities, we have
to idle at the lowest in order not to jump over any low priority tasks
we want to wait upon) than trying to do it all in userspace. Though we
could if we wanted to, it's just easier to use the existing facility
designed for the purpose -- that we were already partially using!
Note that debugfs/i915_drop_caches has only existed since v4.2.

Still all clean on my own pnv n570. Both of those are desktop, whereas
mine is a mobile part, but that shouldn't make any difference...

5,000 iterations later, still no missed breadcrumb or GPU hang. Most
peculiar.
