But that turns
$node->wait_for_catchup('foobar', 'write')
into
$node->wait_for_write_catchup('foobar');
so I don't see much value in it. Also, the patch series from which this
patch spawned in the first place doesn't wait for write AFAICS.
After adding some more POD docs for it, I pushed the one for replay.
