This feature currently groups meta-data from a series of groups at the beginning of a flex group in order to improve performance during heavy meta-data operations. Some light testing on meta-data filesystem and fsck times already show some improvements. This is still very experimental code I meant mostly as a prototype, but comments are welcome. -JRS
