we reopen new version of table.

This leads to the storage engine (SE) not being notified for renames in

rename_table(), because we just juggle with the FRM and nothing
1296
more. If we have an intermediate table, then we notify the SE that
1297
it should become the actual table. Later, we will recycle the old table.
1298
However, in case of ALTER Table RENAME there might be no intermediate
1299
table. This is when the old and new tables are compatible, according to
1300
compare_table(). Then, we need one additional call to

Data is copied. Now we:

1) Wait until all other threads close old version of table.

2) Close instances of table open by this thread and replace them
1183
with exclusive name-locks.
1184
3) Rename the old table to a temp name, rename the new one to the
1186
4) If we are under LOCK TABLES and don't do ALTER Table ... RENAME
1187
we reopen new version of table.
1188
5) Write statement to the binary log.
1189
6) If we are under LOCK TABLES and do ALTER Table ... RENAME we
1190
remove name-locks from list of open tables and table cache.
1191
7) If we are not not under LOCK TABLES we rely on close_thread_tables()
