The test case added in this patch creates System V message queues that it never cleans up. Why is that? We now have this failing on a machine that runs a lot of our bots. Presumably it will start failing on any machine that runs bots after enough runs.
Illustration of the problem:
$ ipcs -q | wc -l 1117 $ ./sysmsg.c.tmp $ ipcs -q | wc -l 1118
