 Description   

The MDEV-27021 test main.show_analyze occasionally fails as follows. Here is the oldest failure that I was able to find:

10.9 e9adc3959ef2e905159dad07b601e41b

 
main.show_analyze 'innodb'               w4 [ fail ]
 
        Test ended at 2022-05-25 13:00:39
 
 
 
CURRENT_TEST: main.show_analyze
 
mysqltest: At line 226: query 'reap' succeeded - should have failed with error ER_QUERY_INTERRUPTED (1317)...

Apparently, the test is making invalid assumptions about the relative execution speed of some threads.
