Review comment:
So previously in the exceptional case, we would fail out before calling
clear, leaving ourselves with buffer position zero, limit N (potentially a
small fraction of the capacity, based on potentially a single event).
Subsequent attempts to flush the buffer can only further reduce the
available buffer space until our limit and position converge. At that point our
`buf.remaining() > 0` condition can never succeed if I'm reasoning through this
correctly, and we cannot write any data.
Great catch!
