5.5.13 perfschema.thread_cache fails when using pool of threads

[Valentine Gostev]

CURRENT_TEST: perfschema.thread_cache
mysqltest: At line 49: query 'select ($con2_THREAD_ID - $con1_THREAD_ID) into @thread_id_increment' failed: 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') into @thread_id_increment' at line 1

The result from queries just before the failure was:
flush status;
SET @saved_thread_cache_size = @@global.thread_cache_size;
set global thread_cache_size = 0;
show variables like "thread_cache_size";
Variable_name Value
thread_cache_size 0

Perfschema bugs will be fixed later if at all. Also, thread cache does not apply to the thread pool.
