forever, cannot be killed mysql_rm_table_no_locks() does TDC_RT_REMOVE_ALL which waits while share is closed. The table normally is open only as OPEN_STUB, this is what parser does for CREATE TABLE. But for SELECT the table is opened not as a stub. If it is the same table name we anyway have two TABLE_LIST objects: stub and not stub. So for "not stub" TDC_RT_REMOVE_ALL sees open count and decides to wait until it is closed. And it hangs because that was opened in the same thread. The fix disables subqueries in CHECK expression at parser level. Thanks to Sergei Golubchik <serg@mariadb.org> for the patch.
