+Abort from ordered index error
+------------------------------
+
+Obviously, index update failure causes operation failure.
+The operation is then aborted later by TC.
+
+The problem here is with multiple indexes.  Some may have been
+updated successfully before the one that failed.  Therefore
+the trigger code aborts the successful ones already in
+the prepare phase.

+In other words, multiple indexes are treated as one.

 Current abort code can destroy a tuple version too early.  This
 happens in test case "ticuur" (insert-commit-update-update-rollback),
 if abort of first update arrives before abort of second update.
