Wow, this sure sounds completely bogus to me. 
Imho CURSORS opened inside a transanction (after BEGIN WORK) are supposed to
be closed (at least with autocommit=yes).  

I do not think COMMIT is supposed to do anything with a prepared 
statement. That is what EXEC SQL FREE :statementid is for.

That would then match e.g. Informix esql/c.
