Infinite loop after LOCK+REPAIR

An infinite loop happens in open_tables after REPAIR TABLE t under LOCK TABLES.

CREATE TABLE t1(x int);

CREATE GLOBAL TEMPORARY TABLE t (x INT);

LOCK TABLES t WRITE, t1 WRITE;

REPAIR TABLE t, t1;

ANALYZE TABLE t;

A table is marked flushed after repair, LOCK prevents eviction. Then, a table is denied to open flush, and backoff is issued – the retries happen in the infinite loop.
