   ha_innodb.cc, trx0trx.h, lock0lock.c, trx0trx.c:
   Reserve the MySQL LOCK_thread_count mutex when printing thd->query of
   an arbitrary transaction; if we are printing thd->query of a transaction that
   we know is currently executing inside InnoDB, then we know that MySQL cannot
   meanwhile change thd->query, and no need to reserve the MySQL mutex; note
   that this patch still leaves open the possibility of races in MySQL's
   thd->query_len
