TODO:
When logging to the binary log, we should log
tmp_tables and transactional tables as separate statements if we
are in a transaction; This is needed to get these tables into the
cached binary log that is only written on COMMIT.
The current code only writes DROP statements that only uses temporary
tables to the cache binary log. This should be ok on most cases, but
not all.
