innodb.read_only_recovery hangs in buildbot

CURRENT_TEST: innodb.read_only_recovery

mysqltest: At line 38: query 'SELECT * FROM t' failed: ER_UNKNOWN_STORAGE_ENGINE (1286): Unknown storage engine 'InnoDB'

The result from queries just before the failure was:

BEGIN;

INSERT INTO t VALUES(0);

DELETE FROM t WHERE a=0;

COMMIT;

# restart: --innodb-force-recovery=3

SELECT * FROM t;

SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;

SELECT * FROM t;

a

1

UPDATE t SET a=3 WHERE a=1;

# restart: --innodb-read-only

# Starting with MariaDB 10.2, innodb_read_only implies READ UNCOMMITTED.

# In earlier versions, this would return the last committed version

# (empty table)!
