Description
The test for MDEV-6619 occasionally fails as follows (observed on the mandatory MemorySanitizer staging builder, but I have seen it in my local environment as well):
main.kill_processlist-6619 w55 [ fail ]

As far as I can tell, this is a race condition. I failed to reproduce this by running the last few tests that had been executed on the same server instance before the failure:
./mtr --no-reorder main.keywords main.kill main.kill_processlist-6619
