Waking an old thread. It seems to me that such an option would still
be useful when rewinding using a stream so as an inconsistent control
file is not read. The default should definitely be to not issue this
checkpoint, but in some environments I believe that this could really
matter, say two failovers followed by two rewinds done consequently.
Thoughts?
