- (NSIndexSet *) selectedColumnIndexes and - (NSIndexSet *) selectedRowIndexes should return an autoreleased copy of the corresponding ivar. Returning a reference to the ivar leads to issues (and behavior different from Cocoa) when iterating thru the indexsets if at a time they would be being altered.
