This is fine as an incremental improvement, but I don't like the way 
we're invoking _note_before_complete unconditionally.  If 
ReportCommitToLog.deleted is invoked *after* ReportCommitToLog.complete, 
then we'll invoke _note_before_complete *after* complete.

I may just have a naming neurosis, but absent a guarantee that 
ReportCommitToLog.deleted cannot be invoked after 
ReportCommitToLog.complete, I think it should be called _note_buffered 
or something.
