Description
The new test main.shutdown fails sporadically with a crash on shutdown, see for example http://buildbot.askmonty.org/buildbot/builders/kvm-deb-debian6-x86/builds/2146/steps/test_3/logs/stdio (server error log: http://buildbot.askmonty.org/buildbot/builders/kvm-deb-debian6-x86/builds/2146/steps/test_3/logs/mysqld.1.err.1)
Below is a slightly modified version of main.shutdown, which seems to increase the probability of hitting the failure, although it's far from deterministic.
