Error: Freeing unallocated data at line 900, 'sql_db.cc'
(
 DROP DATABASE frees thd->db for everything but thd->slave_thread=1
 however we are not slave thread and more bugs could appear if we 
 pretend to be, then we will be good boys and just strdup the value.
 If not DROP DATABASE then THD::~THD() will free the value.
