Hang me

So now the workaround is upstream, we need to find a way to retrigger the
bug...

This patch causes us to unbind everything after each batch - but it also causes
execution to be serialised. So the timing is going to be completely different
versus the IO related hangs... We might try evicting before the batch instead.
