Documented bug fix for 5.1.23-ndb-6.3.8 as follows:

        Consecutive DDL statements involving tables (CREATE
        TABLE, ALTER TABLE, and
        DROP TABLE) could be executed so quickly that
        previous DDL statements upon which they depended were not yet
        written in the binary log.  
      
      
      
        For example, if DROP TABLE foo was issued
        immediately following CREATE TABLE foo, the
        DROP statement could fail because the
        CREATE had not yet been recorded.

Left bug status as Verified pending further commits/merges.
