Comment 3 for bug 1335873

Actually, I am able to reproduce related failures that seem to be manifestations of the same root cause, i.e., memory errors and races while shutting down the client processes uncleanly. These are fixed by https://code.launchpad.net/~afrantzis/mir/fix-shutdown-with-blocked-clients-test/+merge/225172 . If this bug turns out to be a different issue we will revisit.
