> Looking at the code, I find that the logic is unnecessarily complex.
> We indicate in updateReaders that the scanner stack needs to be reset. Then almost all store scanner (and derived classes) methods need to check and actually reset the scanner stack.
> Compaction are rare, we should reset the scanner stack in update readers, and hence avoid needing to check in all methods.
> Patch forthcoming.
