From my standpoint it does not matter if this is Innodb or MySQL part of the code. Innodb is officially supported by MySQL and it was MySQL task to ensure there are no regressions in 5.0 Plus it surely does not help this issue is not properly described in upgrade notes. Sergey,

This was discussed more than once. But the agreement was that this is internal InnoDB issue, it can and should be fixed in the InnoDB. Other storage engines have completely automatic group commit that doesn't need any hooks in the binlog code. Heikki agrees, by the way, and the solution is known. The priority isn't high, though.
