I was merely quoting the oracle note. I myself have never relied on order or
consecutiveness of sequences, only their uniqueness per database instance.
this "new" behaviour is unexpected maybe..but makes sense if you read the
story behind the no segment clause and the fact that a value given out by a
sequence can never be stuffed back into the sequence object. workaround: set
deferred_segment_creation=FALSE and this will not happen
