+    the following heavily relies on the fact that all partitions
+    are in the same storage engine.
+
+    When this limitation is lifted, the following hack should go away,
+    and a proper interface for engines needs to be introduced:
+
+      an PARTITION_SHARE structure that has a pointer to the TABLE_SHARE.
+      is given to engines everywhere where TABLE_SHARE is used now
+      has members like option_struct, ha_data
+      perhaps TABLE needs to be split the same way too...
+
+    this can also be done before partition will support a mix of engines,
+    but preferably together with other incompatible API changes.
