Is there actually any case where it's interesting to delay in that
scenario? I mean that really can only happen if you changed the
configuration to a different delay, or your clock offset
changed. Otherwise we should always reach the consistent point before
the delay plays a role.  I'm tempted to simply only check for delay when
consistent.
